So much more than a greeting card, a Matchbook Mailer "TM" makes a unique package that combines a quality hardcover PPP Petite gift book with a self-contained mailer, which slides open like a matchbox. You don't have to worry about wrapping this gift! Just sign it, seal it, address it, put three first class stamps on it, and put it in a mailbox! A hilarious and witty take on the beloved classic poem.
