Locked horns — though bizarre — aren't as unusual as you might think. There's even a sketch of some stags with locked horns in the classic Gnomes by Poortvliet and Huygen. (Rescuing animals in this predicament is a typical gnome job, apparently.) There's also a painting on the subject by Carl Rungius — Teddy Roosevelt's hunting buddy — called Caribou's Death Struggle that I think is in Vermont's Shelburne Museum, though I couldn't find an image online. Rugius was inspired by finding a set of the antlers himself. You can find the Rungius painting in Gray's Sporting Journal, Vol. 4.6 (1979), p. 42.
