Michelangelo's fingerprints discovered on the butt of a wax sculpture

As revealed in the first episode of the BBC's new series of Secrets of the Museum, the fingerprints of Renaissance painter Michelangelo were discovered on the butt of a wax sculpture at the Victoria and Albert Museum in London. As The Times explained:

The print was discovered after the small waxwork was moved out of an upper gallery, where temperatures were rising rapidly during last year's warm spring, and into the museum's colder basement storage.
