Series 3: Photographs, 1905-2010, consists of digital surrogates of photographs depicting fraternity gatherings, awards ceremonies, anniversaries, and meetings on Long Island, in Brooklyn, and other locations. The photographs also depict the gatherings of the Alpha Wives of Brooklyn and Long Island, which raised funds for scholarships.

Some of the photographs were housed in an album with captions written under the items. In most cases these captions were written by member John R. Rice, Jr. Other photographs had inscriptions on the reverse, or had separate caption documents. All of this information has been added to the item record on CBH's digital collections.
