Battle scene Pop-up BOOK of TMNT 1990

A pop-up picture book published when Turtles’ toys were sold in Japan in the 1990s. It has a small number of pages and can be used as a diorama for Channel 6 office building, Technodrome and Sewer. Also, I think this is something that Turtles Mania often sees, but the TMNT official makes mistakes how to put on the shredder mask. The same applies to the shredder on this cover. His nose has been exposed from mask. He risk getting infected with the coronavirus!
