This is a postcard I won on Ebay. It shows one of the entrances to the old Ouachita Parish High School on South Grand (the second OPHS building). Today it is Ouachita Grand Plaza. What I found interesting was a stamp on the back saying it was, “Trimmed with algonite furnished by Algonite Stone Mfg. Co., St. Louis.” Well, I had never heard of algonite so I looked it up. It is basically crushed marble, Missouri granite, stone, cement and lead ore. Hmm…lead. If you visit the old school, please don’t lick the entryway!
