Another picture came to my attention after the posting of the previous article on the Harris Store in the 1920s. This picture clearly shows the nameplate as Irons Block 1879, instead of Irons Bldg 1875 as was originally posted. Apologies for the error which has been corrected.
Irons Building (Block) in New Vienna 1987 (Daye Hardware), Built 1879
This picture is a photocopy from the files at the Clinton County Historical Society. The caption in the lower right corner reads: Irons Block in New Vienna 3/13/87.
