Beulah, Peel Me a Grape...
When I spotted this painting at the Santa Bárbara Museum of Art, I immediately recognized Severin Roesen, whose work I had seen before in Los Angeles, San Francisco and Philadelphia. And it looks like the White House has one, too!
He is pretty good with fruit, especially grapes. There are several other paintings of his on Flickr.
