Recently I purchased a green Bull Diablo from Guanajuato on EBay™. This was an unusual mask, because the former owner had “permanently attached” a brass pipe to the back of the mask with glue, for the purpose of suspending it from an oak board, apparently because the back edge seemed too fragile to hang it from the old strap mounting holes. He died, his wife was moving to another house, and she was uncertain how to deal with this mask. She offered it for sale with the pipe, the oak board, and a plastic case included. Although it was encumbered by the pipe et al, nevertheless I liked the color and the snakes, so I bought it, hoping that I could manage this problem. Here is the mask.
