A new preview photo shared by Randy Falk of NECA, via a new Instagram account, gives us a look at some new Teenage Mutant Ninja Turtles 1990 Movie head sculpts. The portraits feature Leonardo, Donatello, Michelangelo, and Raphael with all-new expressions. From the size, I’d say these look to be 2-up prototypes for the 7″ scale line. There’s no information available at this time. We’ll update if and when new details are shared. For now, check out the photo after the jump.
