Not-A-Box City by Antoinette Portis
Bunny wants to build a cardboard city.
Bunny stacks one cardboard box on top of another and another.
Bunny doesn't want any help. Bunny doesn't need any help, either.
But what's a cardboard city without friends?
Written and illustrated with the same delightful simplicity that made Not a Box such a hit, the playtime possibilities of a stack of boxes and friendship will inspire and excite any child who has ever journeyed into the world of make-believe.
