There are, as my sagging bookshelves can attest, a lot of books written on the subject of zoos and zookeeping. There are also a few movies on the subject. What there are not, however, are many works of art focused on zoos.
Recently, I stumbled across one of the few that I'm aware of, and by one of America's most renowned artists. Norman Rockwell's Lion and Zookeeper first appeared on the cover of the Saturday Evening Post in January of 1954. Rockwell went on to create over 300 covers for the Post, many of them iconic to this day. None of the rest included zookeepers.
