I gotta say your collection is truly, truly awesome! I actually stumbled upon the Technodrome forum for the first time when I google searched Moo Mesa Animation Cel... And it took me to this thread! I had been looking for Moo Mesa animation cels for a bit. I recently won one on ebay- had some competition, but sniped it at the last minute.
Just wanted to give you major props for your glorious collection of very awesome TMNT merch.
