World book 1964 - Complete set
plus 1965 "year book.
(The other books same condition, are out of frame)
Moderate to poor condition.
Slight Mildew - mostly to cover. Cigarette smoke.
Taking these apart to frame, or to use for crafting, making hide away boxes, whatever... would be quite reasonable. They're kinda interesting, but not valuable, even in good condition.
I'm happy for you to sell whatever you make from this if you wish.
See my other posts for more books.
