my set is also from the 1950’s and is beautiful! Love the gradiating shades of blues and greens! I owned this set (it was missing a couple of volumes) and a brand-spanking new looking one from like 1971, but like Rachel said, it had that retro 70’s cover, honestly can’t remember what the illustrations looked like, it didn’t have that “inviting” look to me. So I sold it. I just love the feel and look of my older set, so yep, I sold the complete newer set and kept my incomplete but beautiful older 1950s set. Guess I’m quirky that way. Nothing like holdling an old, beautiful book. 😉
Eventually I would love to buy a complete new set (where all the volumns match, if I buy missing volumes they may not be in the same condition, there may be more/less fading, etc). But in the meantime I’m quite happy with what I have.
