A clever vintage style greeting card that doubles as a bookmark! We use a library 'date due' card and retro style book pocket to create a unique way to send some love to someone special. Each library card is 3.5" x 5" and is packaged in clear cellophane with a 4.5" x 5.25" red envelope. There is room on the front or backside of the card to write a personal message! Minimum 6 per design
