Ultimate Challenger!: A Book of Picture Riddles

Jean Marzollo and Walter Wick return with two new additions to their popular series. The paper-over-board I Spy Ultimate Challenger! A Book of Picture Riddles boasts brand-new riddles as well as old favorites, such as ""The Secret Note"" from I Spy Mystery and ""Inventor's Workshop"" from I Spy Spooky Night. And three bestselling board books-Little Letters, Little Numbers and Little Book-are now being offered in a boxed set, I Spy Little Learning Box. Rebus-like photos alongside the riddle on the left help youngest spies locate the objects within the bigger picture, opposite.
