I've found some old sets of penguin shaped skittles or ten pins, but I haven't been able to find an exact match for these, which I might take for unnaturally multi-colored crows (and it does seem they'd make pretty good shooting targets, too)-- but I'm really not sure. In any case, I just really like the look of them lined up in a row.
3 3/4" t x 1" diameter at base. Sold as a set of 4. In great structural shape, and to my eye they've been knocked around just the right amount. (I forgot to photograph them all facing the opposite direction but they're just as good from the other side.) Earlyish 20th century I believe.
