Mystery Photo #79: Piper & Johnson
This cabinet card photo is from the Piper & Johnson studio at 227 E. Superior St., Duluth. Today that location is where Greysolon Plaza, the former Hotel Duluth, sits. Since cabinet cards were popular at the end of the 19th Century, the Piper & Johnson studio must have been in a building that predates the Hotel Duluth, which opened in 1925.
