From Pittsburgh Streets

To do

"Above: Modern-day signs on streets once part of Allegheny City mark the prominence of tanning and leather in local history. The Lappe family (see article, page 43–44), owners of the tannery shown on pages 32–33, also lived in the area. The street bearing their name (now a walkway in many places) crosses Haslage Avenue high above the old leather and slaughterhouse district in Spring Garden." (p. 34)
