CDC? — William Steig

To figure out William Steig's word puzzles you need merely read the letters, numbers, and symbols aloud. If at first the messages aren't clear, there are clever pictures accompanying each one to give you hints. Some are easy, some are hard, but all are a hilarious treat when the phrases are decoded. This is the original 1984 edition, with black-and-white drawings. Also included is an answer key at the end.
