Collecting interests
Barkhausen investigated and studied the field of United States postal stationery, and created one of the most significant collections of the kind. It included cut squares, essay submissions to the Post Office Department, proofs created prior to the final printing process, and postal cards.When he decided to dispose of his collection in 1955, Barkhausen broke the collection up into two parts: one part he donated to the Philatelic Foundation for use in their reference collection, and the second part he placed for sale with H.R. Harmer, Inc., with the selling taking two years and fetching spectacular prices.
