Originally published in 1948, Billy's Picture by H.A. and Margret Rey, illus. by H.A. Rey, centers on an artistically inclined bunny who tries to draw a self-portrait. Billy's animal friends add their own features quills, wings, a trunk to his drawing, resulting in a cuddly chimera. Rey's priceless retro illustrations contrast Billy's growing dismay with his friends' excitement at contributing to the drawing. ( Aug.) .
