Bees Love Truth

Speaking of old movies, is this (from here) really what the Monster from the Id was supposed to look like? Check out the little playset-looking thing (from here). I mean, where'd they get the coloration? All we ever see of it is shots like these. Maybe there is a maquette somewhere that people are going from. I do enjoy the apishness (probably will never say that again) of the model, there; it's an interesting distortion of its human source.
