Artists Jack Kirby, Neal Adams, Hergé, and Jim Lee are common targets of swipes, though even those artists may not be above reproach; Kirby was known to have swiped from Hal Foster early in his career. Similarly, many Golden Age artists kept "swipe files" of material to be copied as needed. Certain contemporary artists have become notorious for their swiping, including Rich Buckler (who favors Neal Adams and Jack Kirby), Rob Liefeld (many artists), Keith Giffen (José Antonio Muñoz), and Roger Cruz (Jim Lee and Joe Madureira).
There is a long tradition in comics of using fine art as "inspiration" as well. Most observers do not consider this as objectionable as swiping from another cartoonist's work. Examples include Art Spiegelman swiping an image of the Russian artist M. Mazruho's in Maus, Eddie Campbell swiping Diego Velázquez, and Jill Thompson swiping the work of Arthur Rackham.
Cartoonists have also swiped images from mass media and commercial art. Examples include Batman creator Bob Kane repeatedly swiping from early 20th-century illustrator Henry Vallely, Greg Land repeatedly swiping pornography as well as many popular comic book artists, 2000 AD artist Mick Austin swiping an image of Toni Shilleto's from Mayfair: Entertainment for Men, Jon J. Muth swiping a 1940s photograph, and David Chelsea swiping from Spanish pornography. Sometimes the swiping happens "in reverse," as in the example of an illustration from Organic Gardening magazine swiping the iconic Kirby cover for Fantastic Four #1.
Swiping brings to mind the amusing conundrum of whether an artist can swipe from himself. One example is two almost-identical Peanuts strips by Charles Schulz done almost ten years apart. Another comic strip-related ethics question was invoked by latter-day Nancy artists Guy & Brad Gilchrist swiping Nancy creator Ernie Bushmiller.
Though not technically swiping, some artists have made a career "cloning" other artists. Phil Jimenez has been quite open about his work being modeled on George Pérez's, though he has never been accused of directly swiping a Perez drawing. Bryan Hitch started off as an Alan Davis "clone." Bill Sienkiewicz's early work was blatantly derivative of Neal Adams, as was Tom Grindberg's, Michael Netzer (Nasser)'s, and Mike Grell's. Industry veteran Dick Giordano maintained that cloning is not only acceptable, but actually preferable, when an artist fills in for a regular artist on a title.
Pop artist Roy Lichtenstein made a splash in the 1960s with his "appropriations" based on the work of Kirby, Russ Heath, Tony Abruzzo, Irv Novick, John Romita, Sr., and Jerry Grandenetti, who rarely received any credit. Jack Cowart, executive director of the Lichtenstein Foundation, contests the notion that Lichtenstein was a copyist, saying: "Roy's work was a wonderment of the graphic formulae and the codification of sentiment that had been worked out by others. The panels were changed in scale, color, treatment, and in their implications. There is no exact copy." Comics industry figures don't have such a sanguine attitude about Lichtenstein's swipes.
Similarly, Canadian artist Kevin Mutch once drew an entire comic book entirely based on swipes. Mutch's 1993 comic Captain Adam was a "narrative collage" of images and texts from over fifty separate Silver Age and Bronze Age comics, randomly put together to form an original story.
Comics pastiches are blatant uses of swipes, cloning, and appropriation, usually using the same characters as the original source. French-Canadian cartoonist Yves Rodier is known for his many Tintin pastiches, as is the anonymously written comic book The Adventures of Tintin: Breaking Free. In his Masterpiece Comics series, American cartoonist R. Sikoryak cleverly mixes exact cloning of famous cartoonists' styles with classic literary texts, creating unique comics "mash-ups." Alan Moore and Rick Veitch's 1963 series is another example of pastiche in comics form, as are the many take-offs of the Charles Atlas ads found in old comic books.
In comics, it is understood that the difference between a swipe and an "homage" is generally whether the source is directly acknowledged — as opposed to being exposed by a third party. Throughout the history of the medium, artists have engaged in homages — most often of well-known cover images like Action Comics #1, Detective Comics #27, Amazing Fantasy #15, and Fantastic Four #1. (John Byrne is particularly fond of doing homages to the latter, having produced at least seven versions to date.) Some observers find homages as objectionable as swiping.
Swiping watchdogs 
From 1991 until at least 1997, the industry magazine The Comics Journal kept a "Swipe File" which documented perceived swipes in the comics field,[volume & issue needed] a tradition that continues on the TCJ website.
Artists accused of swiping 
|Chester Brown||Joe Orlando|
|Rich Buckler||Neal Adams||Buckler has a dubious reputation as one comics' top "swipe" artists, with his early work in particular filled with "homages" to artists like Jack Kirby, John Buscema, and Neal Adams. After being publicly accused of the practice by The Comics Journal in the early 1980s, Buckler denied the charges and sued the magazine for libel; he later dropped the suit.|
|Michael Allred||David Chelsea||Allred denied the charges.|
|Denys Cowan||Gil Kane|
|Glyn Dillon||Jaime Hernandez|
|Steve Ditko||Will Eisner|
|Ron Frenz||Jack Kirby|
|Keith Giffen||José Antonio Muñoz||Giffen has acknowledged Muñoz's influence, and in 2000 referred to the controversy this way:
|Bob Kane||Alex Raymond||The classic Batman pose on the cover of Detective Comics #27 (the first appearance of Batman) is swiped from a 1937 Alex Raymond drawing of Flash Gordon.|
|Gil Kane||Jack Kirby|
|Jack Kirby||Hal Foster|
|Alan Kupperberg||Gil Kane|
|Rob Liefeld||Brent Anderson|
|David W. Mack||Adam Hughes||Mack admitted the Hughes swipes online:
|Todd McFarlane||Otomo Katsuhiro|
|Joe Phillips||Barry Windsor-Smith|
|Andi Watson||Mike Allred|
