Shorpy's, great site - been around a little before, but not in markets and stores...
I'm sure my mom or neighbors used Oydol, have seen it in their laundry areas, along with 20 Mule Team Borax.
The eggs in the picture, on the floor - not kept cool? And what's Joe Phillip's Co. The Original Scrapple, next to the Dayton scale on the counter? Really interesting - thanks for posting.
