This building seems to have been put up for Allen Kirkpatrick & Co., but for years it was the home of the Pittsburgh Tag Co., as this ghost sign tells us. It has been vacant for some time.
The Pittsburgh Tag Company was founded in 1927, as we find in the Paper Trade Journal, December 15, 1927:
Pittsburgh, Pa.—The Pittsburgh Tag Company, care of Charles F. C. Arensberg, 834 Amberson street, Pittsburgh, recently organized with a capital of $50,000, plans the operation of a local plant for the manufacture of paper tags and kindred specialties. Mr. Arensberg will be treasurer of the new company; James M. Graham and Jonathan S. Green will be directors.
