Mirabelle is a super hero to so many kids. We are so excited her book series encourages new readers. We were asked to design this for a library in NY and with such great response from our fans asking if they could own one we are making it available to you. The poster is 13 x 19 inches on a heavy glossy stock. perfect for framing or just taking up on the wall so everyone remembers to HAVE AN ADVENTURE WITH A BOOK!
