Here are a few more things:
Dark Horse miniatures MOC- $5 each. These are not TMNT but come from the same era as the TMNT miniatures.
Gen finger puppet- $3. Ok, he's not TMNT either, but he's from Usagi Yojimbo..close enough
animation drawing from "Camera Bugged" 1989- $10.
uncut TMNT pie stickers set- $3. I think this may have a crease thru it now.
3 TMNT movie cards cut from the back of TMNT Cereal- $2.
not really ninja, but definitely turtles- $4. The large one is hollow and glass. The two small colored ones are plastic. The white one is stone.
