You might find this store a bit intimidating, but it's the coolest thing ever! I just bought my gf a book from 1661 there. Really. Not a typo. And they have a huge section dedicated to old maps, and they sell lots of cool antique prints for $10 and $20. This is a great place to go if you like old objects, are searching for an out of print or antique book, or want to purchase a truly unique object for yourself or as a gift.
