Unsure if this is the right place and I know it’s a bit of an ask.

My wife recently expressed that she wished she had an encyclopedia set that her grandmother owned in the 90s. The set was given to a cousin when she passed who donated it, which crushed my wife as she was attached to the set sentimentally.

I don’t have much identifying information other than the set contained a book with children’s stories, my wife vividly remembers one about a monkey. I don’t want to ask too much from my wife to not spoil the surprise or get her hopes up. I am following leads from family but no luck so far.

Any help or direction would be greatly appreciated.
