It's titled "Casual Friday", done by Margaret Organ-Kean, whose work has been seen on Magic cards and other places. If you want to see the Real Thing, check out the Animals Gallery at organ-kean.com It could be titled 'Penguins in Pepperland', they would be right at home swimming around the Yellow Submarine.
The print was a Christmas gift from my brother Jim, and now I have to think of something terrible to do to him.
