Lost & found childrens toys & games in Manhattan

Lost child's medium superhero Halloween costume with red cape and mask near Central Park bench.

I lost my child's superhero Halloween costume while we were out trick-or-treating around Central Park on Halloween night. It’s a size medium, with a red cape and a mask. I remember taking it off for a photo, and I must have left it behind on the park bench. If anyone finds it, please let me know, my kid is really upset about it!
