Junior Deluxe Editions Pride and Prejudice
Well, unfortunately this one doesn't have an ISBN. It is a Junior Deluxe Edition, published in 1954, illustrated by Edgard Circlin. I found mine browsing eBay. There is apparently another cover, a pink one, which I am still searching for! You can check Abe Books here to see if they have one of these rare mystical creatures in stock!
