Check it out! This bookishly festive collection of clever cards combines two of our favorite things: libraries and birthdays. Each 4½"x6¼" note card features a classic - and functional! - library-card checkout pocket on the front, while inside is a funny reading-themed birthday greeting: "Shhhh...Keep your age filed in the 'mystery' section!"; "I've been checking you out! Happy birthday to a real 'page turner'!"; and "Everyone has a story...Yours just happens to contain more chapters than others!" We're offering a set of six cards (two each of three designs, with envelopes) to keep on hand, so your birthday wishes to friends and family will never be overdue.
