A very odd costume, indeed. One can probably write a fascinating article on the change from single character to multi-character illustration on the costume itself, but there's another article in how suitability of mask to costume has varied over time and sociological development. I'll just note that the mask is completely mismatched to the costume. I'm guessing there was a production run of the mask for some other reason than this specific costume and Collegeville decided to save money and re-use the masks with this idea. If not, I'd be stumped as to who green-lit this one.
