About this photograph
This is a copy photograph created by Theodor Horydczak in 1920. The original nitrate negative measures 8 by 10 inches and is now part of the Library of Congress collections.
Horydczak worked as a commercial photographer in Washington, D.C. His photographs are held by the Library of Congress as a named collection.
The record identifies the subject only as a man. No name, age, occupation, or other details about the sitter are given. Copy photography was a common commercial service, allowing clients to preserve or reproduce existing portraits by creating new negatives from original photographs or prints.
The nitrate negative format was standard for professional photography in 1920, though nitrate film was chemically unstable and required careful preservation. This accounts for the photograph's subsequent transfer to an archival institution.
Compiled from the catalogue record and reference notes on the formats and events involved. The archive record above is the primary source.
