My wife's artist friend loaned us a beautiful old book about a famous restaurant and it's menus - Del Monicos. It was handsomely illustrated. Including the feast for Lincoln's inauguration dinner etc.

Original binding but for some added librarians' tape to keep the covers stable. She paid $6 at a thrift shop.

I googled a bit - worth $400 to $600! She doesn't care; its all about the beautiful illustrations for her.
