British Museum website: "Five versions are known of this composition with wild animals, probably all copies after a (now lost) original by Pieter Bruegel. The BM sheet and one in the Fondation Custodia, Paris (inv.no.8025) are qualitatively the best. The Paris sheet has traditionally been attributed to Jan Brueghel the Elder, while the other versions are considered anonymous copies. Three other versions are kept in the Art Institute of Chicago (inv.no.22.1932) and the Musée du Louvre, Paris (inv.nos.20724 and 20725)."
