Kermitage 1983 signed poster with Kermit and Piggy

[muppetenvy]

hey! I have a 1983 Kermitage poster from the Berry Hill Galleries in NYC that is signed in gold "Kermit the Frog" and "Miss Piggy". Very cool poster of Kermie and Piggy dressed in Victorian outfits in the bedroom...even Foo Foo is in this one! It is from the Kermitage Collection entitled "Miss Piggy's Art Treasures". It comes with a letter from the Henson company and a description of the artwork entitled "The Marriage of Froggo Amphibini and Giopiggi Porculini".

I was wondering if anyone knew anything about this, I love the poster but am pretty clueless about how it came about at this gallery auction. Anyone???

here's a link for the picture of the poster...
