"Gotham" screen matched spider box from season 2; episode 2, titled knock knock. Theo Galvan tortures Mayor Aubrey James using this box, in which he threatens to place a spider inside the box with the major.
The box, which appears metal on screen, is in-fact leather. It is quite a substantial prop and very heavy.The inside has a cut out which allowed for actor Richard Kind to place the box over his head. The bottom is removable with Velcro, seen in final photo.
This allowed production to place the neck pieces safely around Richard's neck. See this exact prop here. Props from Gotham are hard to locate, but this is a rare find that's sure to look amazing in your DC collection. Measures 13"x 14" x 14.
