I have a copy of "Now We Are Six" by A.A. Milne from 1927. Are you interested in purchasing it or do you know someone who might be? I also have children's, 70's and 80's albums from pop stars and shows.

When you have books that are from that era of they are in good condition and useful, this is not the place for you. People will say Ebay but I say No! Go to a mint condition artifact show and sell it there to price the real value of your books cause Google Reviews is just that (reviews) this is my best advice to you for the worth unless you take it to a pawn show which may sell it but give you a fraction of the true value. It's a (Courier) you need there in N.Y but if you live someplace else look for them I hope it works out.

You'd probably do much better at a local independent vintage book store. This isn't really that kind of store.
