Sam at BLAG'The Pittsburgh Portfolio of the H.H. Seiferth Sign Company'
This remarkable photographic archive contains the output of one sign firm in the first 30 years of the twentieth century. I have edited a selection for presentation at bl.ag online.
Thank you to Christian Shaknaitis for telling me about the archive, and to the Detre Library & Archives at the Heinz History Center for permission use the images.
