The inside cover of "Wonderful World of Peanuts" (Fawcett World Library), purchased around 1960, is quite brown and the whole book is yellowed from sun exposure. It's a used book, but I've listed it because it includes the character introductions at the beginning, etc. Size is approximately 11 x 18 x 1 cm. (The bonus book "You're a Winner" is also from the same series.) There is yellowing and some wear, but if anyone is interested, please consider it.
