I saw these old postcards in an Antiques store. Two of them were sent through the mail and have postmarks of 1908 and 1912. The others appear to be of similar vintage. Most of the captions can be read if you click on the photo for a larger image.
These photos were the best I could manage with the postcards being in plastic sleeves and under indoor lighting. I debated whether to buy any of them at $2 each. I already have a lot of misc train stuff.
