The Jumpman logo is a silhouette of Michael Jordan performing a dunk. Beginning in 1985, the Jumpman photo or logo always accompanied "Jordan (affiliated with Nike)" branded products, even when the only word displayed on the product was "Jordan".
The Air Jordan III, released in 1988, was the first Air Jordan shoe to feature the Jumpman logo, replacing the "Wings" logo, which had been a feature of the Air Jordans I and II. This model was one of the most popular ever. The Jumpman logo would retain a fairly consistent look throughout the Air Jordan line's history, except on the Air Jordan VIII, on which it was reminiscent of a peace sign.
In 1993-94, Nike ran a series of Air Jordan commercials pairing Michael Jordan with Warner Brothers' owned Bugs Bunny. As a tie-in, Nike created a line of merchandise which featured a spoof of the Jumpman using Bugs' silhouette, combined with a "Hare Jordan" caption. This led to the film Space Jam and also on that movie they showed him performing the jumpman but spoofed it by having him dunk from half court unlike his actual dunk.
