This one stumped me, until a colleague looked at the sign in the photo and said, “Swap Shop”. She was right!

The Swap Shop was located at 905 DeSiard Street, at the corner of 9th and DeSiard, across from the City Cemetery. It was just down from the Miller-Roy building. WOW!
Love the Chesterfield Cigarettes ad on the side of the building!
