Alfred H. Caspary (1877–1955), of New York City, was a philatelist responsible for assembling one of the finest collections of United States postage stamps.
Around the time Ferrary’s Buenos Aires 1859 1p "In Ps" tete-beche pair reached the market in 1923 and was acquired by Alfred Lichtenstein, another example of the Buenos Aires “Barquitos” “in Pesos” tete-beche was discovered in Germany and sold to Alfred H. Caspary.
Harmer auction house between 1955 and 1958, realizing record prices for many of the finest items in the collection.
After Caspary’s death, H. R. Harmer sold his South American collection in June 1958.
Following Caspary the “In Peso” vertical tete-beche pair was owned in succession by Lars Amundsen, Joseph Schatzkes, John R. Boker Jr., and Gabriel Sanchez.
