Interior of greengrocer's (fruit & vegetable) store, circa 1920s
If you click the above image and look closely at the rear wall upper you will see one of the posters promoting fruit listed in recent posts here as well as several others.
Would you like a bottle of fizzy drink to go with your cauli today? Grab one off the rear shelf.
Unfortunately, this store and the photographer are unidentified. Get with it, people! Write important info on the back of your photos for posterity! (Ok, yours truly regularly transgresses on this very point).
