Post cards are an interesting area of collection when it comes to documenting history. You see a lot of things that you never knew existed and are not easy to find photos of otherwise. Especially if you get RPPC. Back in the day people would have short runs of RPPC's printed and send them off to their family and friends. I've been working on scanning a collection of cards from Southern California beach areas going back to 1900. Here are some from 1911, the Ship Cafe in Venice, CA.
