Here today is a vintage I am guessing pretty rare, Lewal Pharmaceutical Company envelope with Minnesota Statehood stamp. Postmarked Chicago 1959. Has some wear form age.  See photos and ask any questions. I do my best to describe all items. Sometimes I miss things.. Please Please ask questions. Thanks for bidding and good luck. Check out all my items for some great finds. Lots of cool stuff at my sales. I can combine shipping on most.
