Each package contains 50 Books for Baby and 50 Diaper Raffle Cards to include with baby shower invitations. Books for Baby cards say "One small request that's not too hard, please bring a book instead of a card, please sign your book with a line or two, letting baby know this book is from you" Diaper Raffle cards say "Bring a pack of diapers for a chance to win a prize!" All cards measure 2 in x 3.5 in.
