Correspondence, speeches, clippings, campaign material, photoprints, brochures, and programs reflect Crandon's activities and interests as a Dade County commissioner, sponsor of the Miami Civic Music Association, and lover of nature. Two large scrapbooks, covering the years 1942-1950, contain material on county matters, especially parks and health services; the expansion of the airport; Miami Civic Music activities, Crandon himself, and his family. There are a number of private and public testimonials given at his retirement from the county commission. A third smaller scrapbook (1962-1970s) concentrates on the "Crandon amendments" to the Metro charter in 1962. Two folders, housed separately, have letters from constituents and material from his 1932 campaign for election as commissioner from District 1. Correspondence includes a 1948 ALS from Philip Wylie on the Key Biscayne railroad and a 1942 ALS from David Fairchild on Crandon's recovery from a serious illness.

Letters to and from Charles H. Crandon, then Chairman of the Dade County Board of Commissioners, pertain to several requests for assistance from the county welfare funds. Letters from Crandon are carbon copies; others are originals
