"CDB!" is a children's book written by
William Steigfirst published in 1968. The book is a collection of "letter codes." CDB! means "See the bee!" The illustrations that accompany the codes give an indication as to the solutions. The book was updated by Steig over 30 years later by adding some color to his illustrations and adding an answer key to the back of the book. Steig followed this book with a sequel, "CDC!" ("See the sea!")
