The next image is certainly from a later period than the first, judging from the more "modern" appearance of the store and the salesman. We can read some of the signs (the one in the center says: "Our terms are cash. These prices positively do not warrant any extension of credit."), but they don't really help us to locate this store. But as for the date, do you think, around 1920?
This is probably the most recent of the images, but perhaps not too far in time from the previous one. 1930s, perhaps? Clothing and shoe styles help to date this photo. (Look at the really short tie of the man on the right, for example.) Again, we don't have much else in the photo to help us determine the location of the store. We do see the prices for the shoes, which makes the scene even more interesting, and might be helpful for any shoe historians who view the image.
If you have any observations of your own -- especially if you recognize any of these stores or people -- feel free to add your comments.
