Black market for art

The black market for art includes works stolen from collections or looted from archaeological sites, as well as forgeries and banned pieces. Thieves often encounter more difficulty selling stolen masterpieces than obscure works, as collectors able to afford such art are generally sophisticated enough to hear news of the theft.

In this update, Grove Art publishes 32 emendations, including adjustments to images in articles such as Athens, Florence, Philadelphia, and Viking Art.
