This originated in a life drawing of my roommate Jeff lying on the sofa with his Basenji, Fancy. To fill out the composition for the round plate format, I added Bones as a puppy sleeping with his toys, although this would be some years later in real time.
To see the original drawings go to Man and Dog on Sofa . I don't seem to have the photo of Bones sleeping with his toys up on the site, a terrible omission.
