The general form is minimal: a square box containing a few abstract pictorial elements with a caption (or several) giving a humorous explanation of the picture's subject. For example, a Droodle depicting three concentric shapes – little circle, medium circle, big square – might have the caption "Aerial view of a cowboy in a Port-a-john."
The trademarked name "Droodle" suggests "doodle", "drawing" and "riddle". However, the form of the droodle – a riddle expressed in visual form – has earlier roots, for example in a drawing (indovinelli grafici) by the Italian painter Agostino Carracci (1557–1602), and the term is widely used beyond Price's work.
Droodles are (or were) purely a form of entertainment like any other nonsense cartoon and appeared in roughly the same places (newspapers, paperback collections, bathroom walls) during their heyday in the 1950s and 1960s. The commercial success of Price's collections of Droodles led to the founding of the publishing house Price-Stern-Sloan, and also to the creation of a Droodles-themed game show, Droodles, on NBC in 1954. There was also a droodle-based game called "Mysteriosos" on HBO's Braingames. Series of newspaper advertisements for the News and Max brands of cigarettes featured cigarette-themed Droodles.
Appearances in art and popular culture
One of Price's original Droodles serves as the cover art for Frank Zappa's 1982 album Ship Arriving Too Late to Save a Drowning Witch. Price's other captions for that drawing include "Mother pyramid feeding her baby."
In the Mexican comedy series El Chavo del Ocho, in one episode of 1974, Profesor Jirafales arrives with several drawings that resemble Droodles (made by Quico and Chavo) and takes them to Quico and Chavo to explain what they drew.
