Recent work on the Duluth Plumbing Supply building at 322 W. Michigan St. — now SPS Companies — has made more visible the words painted on the back side more than a century ago. The bottom line reads “Wholesale Flour, Feed, Grain and Hay.” The top line originally read “Wright-Clarkson Mercantile Co.” but appears to have later been painted over with some other words.

The old-timey photo is via Shorpy and is dated “circa 1905.” St. Louis County property tax records list the building as constructed in 1910, but that’s potentially not accurate.
