The Muppets make their first appearance in Acme's popular and growing Disney Underground line with this San Diego Comic-Con 2011 Exclusive The Muppets variant screen print by Dave Perillo entitled “It's Not Easy Being Green.” Limited to just 100 pieces, this 18"x24" signed and numbered 4 color screen print can be purchased at Acme’s SDCC Booth #5629 for $50 each.
For those of us unable to attend SDCC, there is the standard version of Perillo's The Muppets screen print (which you can see above) that will eventually be available for purchase via Acme’s online store.
