Bumble-Ardy has evolved from an animated segment for Sesame Street that aired in the early 1970s to a glorious picture book about a mischievous pig who has reached the age of nine without ever having had a birthday party. But all that changes when Bumble throws a party for himself and invites all his friends, leading to a wild masquerade that quickly gets out of hand.

In this highly anticipated picture book, Maurice Sendak once again explores the exuberance of young children and the unshakable love between parent (in this case, an aunt) and child. Bumble-Ardy is the first book illustrated and written by Sendak since Outside Over There in 1981.
