The major influence of dealer Leo Castelli and his gallery on the development of mid-to-late twentieth century modern art in America is well-documented through business and scattered personal correspondence, administrative files, exhibition files, extensive artists' files and printed materials, posters, awards and recognitions, photographs, and sound and video recordings.

Fred Wiseman, along with J. W. Peters and D.C. Prentiss, built a biplane named the Wiseman-Peters. During July 1910, both Peters and Wiseman flew the Wiseman-Peters and the following year Wiseman entered the 1911 Aviation Meet at Selfridge Field, Michigan. On February 17, 1911, Wiseman made the first airplane-carried mail flight officially sanctioned by any local U.S. post office and made available to the public when he carried mail, a bundle of newspapers and a sack of groceries from Petaluma, CA, to Santa Rosa, CA. After the 1911 season, Wiseman gave up flying. This collection consists of a large scrapbook. Inside the scrapbook are newspaper clippings, correspondence, 1st Day Covers, race tickets, and photographs chronicling both Wiseman's automobile and aviation careers.

This collection consists of correspondence, memos, newspaper articles and logbooks concerning the flight.
