Yes, that is a guinea pig comb/head piece. It was created by Reid Peppard, a British taxidermist. Her pieces take animals commonly perceived as vile pests and turns them into fashion items. Peppard says, “…when they become sculptural headpieces, necklaces and cuff-links, the specimens cease to be waste and become objects to behold. RP/ENCORE makes use of the city’s leftovers.” Would you be comfortable wearing this stuff?
