The E. G. Barnhill Collection contains negatives of Florida homes and birds, as well as glass plate negatives of Florida scenes. The collection also contains hand-colored postcards by Barnhill depicting Florida scenes (ca. 1910s-1930s), early Florida ephemera, several biographical pages and scrapbooks put together by Barnhill with many resourceful historical clippings from the early half of the 20th century on pirates, Native Americans, archaeological exploits, early technology, and treasure hunting.
The Finlay B. Matheson collection includes more than 2,411 photographs; 112 maps, surveys, and architectural plans; and 13 books related to William John Matheson and his immediate family. Estate documents and other documents containing historical and biographical information pertaining to the Matheson family and their various business ventures can also be found within this collection, as well as drawings, postcards, and some of the first aerial view photographs of Key Biscayne, Coconut Grove, the Miami River, and the Florida Keys. Florida's landscape during the early 20th century is captured throughout the various albums and scrapbooks and attests to a more leisurely lifestyle before the advent of skyscrapers and multi-lane highways. Furthermore, the collection provides an in-depth glimpse into the burgeoning social life of early inhabitants who gathered at the Biscayne Bay Yacht Club.
