If you're into vintage cookbooks, Booklady Cooks has a great selection from 1950 to 1990. The condition of the books varies, so make sure you read their descriptions when choosing. I personally love reading them and don't mind some wear and tear because it adds to the vintage charm. Besides the wide selection, I also enjoy the illustrations and menus that transport me to another time and place. You can get a sense of the meals and celebrations that were part of people's lives. The prices range from $5 to $20.
