What is the starting salary for a art historian?

Minimum wage (or possibly less) in the exciting and fast-paced world of food service.

There are essentially no jobs for art historians other than teaching art history. That is, there are lots of jobs art historians can do, but their training doesn't necessarily make them much better than any other liberal arts major at it. Possibly a museum curator, but unless you're related to someone on the board of directors of the museum, that's probably notgoing to be an entry-level job.
