>>7017197It's a piece from the Teenage Mutant Ninja Turtles Sewer Lair Playset from like 2012/2013. I got most of it for like 10 bucks used and it's a great piece on it's own. But just by removing a few pieces and popping it in half it also makes a great backdrop. It's sadly a bit too small to fully scale with Marvel Legends, but it's not bad enough where it ruins the look of the display.
The bottom half also works well on it's own. It's a nice way to add levels and depth to a display without needing to do any actual work. Though if one were to paint it up, I'm sure this thing would be fantastic.
