Original Teenage Mutant Ninja Turtle Action Figures
When I went to the lady's house she had a bunch of her son's old toys laid out for sale. I pretty much ignored the Star Wars figures and was drawn to these four fellows and I think a couple more early TMNT figures. I even picked up the Turtle Van, but it wasn't in the best of condition so I have since moved it out of my collection.
The Teenage Mutant Ninja Turtles were a huge hit (no surprise there, right?) so later releases of the first few figures were made with solid plastic heads.
I'm glad I ignored the Star Wars stuff and instead bought up these guys!
