I love this old picture. Click to enlarge to see all the detail. I don't know what grocery store this is or what city, but it is just full of interesting bits and pieces from the clothes shoppers and clerks were wearing to the massive amount of items on the shelves. And, the back wall has a large sign telling people what aisle you'd find things in. Each aisle had a large number on a pole unlike today where each aisle has its own sign with what you'll find there.
