Summary
Image captured from The Tracey Ullman Show short "The Krusty the Clown Show".

Fair use for Krusty the Clown
This image is being linked here; though the picture is subject to copyright I feel it is covered by the U.S. fair use laws because:
 * it is a low resolution still of a television series;
 * it does not limit the copyright owners rights to sell the film in any way;
 * it illustrates the character's first appearance in the show and allows the reader to compare how the character's appearance has changed over the years.
 * There is no known replaceable non-fair use image.
