The central graphic of the shirt is the Muppet Movie rainbow logo, complete with Kermit's head in the 'O' of "MOVIE." The image is copyrighted Henson Associates, Inc., 1978. A unique feature of this shirt is its size and cut. Above, it is pictured as a size L, yet on today's scale the shirt would likely be a size M at most. This is due to the different dimensions used for men's shirts in the 70s and 80s (a distinction which is helpful when trying to determine the age of an item like this one when no copyright date is included).
