I have a LGB "Surprise for Sally", 1950. I think it's an "A" but I'm not sure. I can't find a letter on the last page, I looked pretty closely. It looks like photos I've seen of the "A" of this book. The back cover has a list of "The Little Golden Library" with an ornate gold border. Any idea of how I can tell what edition it is? If it's an "A", any idea of the value? It's in good condition and I see 2 have sold on ebay for $35 and $51. Thanks.
