Letters

This handbook contains everything you need to know to get started stamp collecting. It was written by prolific philatelic author Stephen Datz in consultation with famed philatelist Wayne Youngblood. The book covers the essentials and illustrations augment the text. The authors define philatelic terms, discuss all the different ways stamps are hinged, and dive into the history of stamps. 

Joseph Hirshhorn mingled and corresponded with numerous artists and dealers while amassing his art collection. Included in the Joseph H. Hirshhorn Papers are letters and images documenting his relationship with Georgia O'Keeffe. Other frequent correspondents are Hirshhorn's wife, Olga, and O'Keeffe's longtime assistant/curator/dealer, Doris Bry. The correspondence documents a mostly friendly (but sometimes contentious) relationship between O'Keeffe and Hirshhorn.
