Stamp collecting was one of Dr. Andersson’s hobbies, particularly stamps related to deafness and Swedish and other international stamps. This series includes stamps, cancellations, and First Day Covers from many deaf-related events, including World Games/Deaflympics, World Congresses of the WFD, and events at Gallaudet. There are particularly large collections of stamps and First Day Covers for the 1980 Helen Keller/Anne Sullivan stamp, 1982 Thomas Hopkins Gallaudet stamp, and the 1993 American Sign Language stamps. Also included is a large collection of envelopes and postcards from Dr. Andersson’s correspondence (a few still have letters in them) that he appears to have saved because they had interesting stamps.

Of particular interest are some Japanese envelopes and stamps from the mid-1940s, which passed through military censorship during World War II, as well as an assortment of stamped, canceled envelopes from Sweden in the 1940s and 1950s.
