The great majority of items in this file are 8"x10" black and whites prints but the prints range in size from 3.5 in. square to 8x12 in. Some color prints along with some slides, negatives, positives, and contact sheets are also included in the photograph file (though unless otherwise indicated, folders contain prints). Many are official photos taken by government photographers and include formal, casual, and candid shots but also included are some "snapshots" and other photos taken by amateurs. Some of the folders contain notes, lists, or letters that relate to the photos. Many of the photos are of Baker with constituents, interns, or pages but photos of Baker at meetings, receptions, and giving speeches along with photos that do not include Baker are also included. Quite a few of the photos are file copies; that is, they have photo lab tracking information printed or written over the image. Most of the title and date information was taken from the envelopes used to store the photos in Baker's office. A few photos (primarily snapshots attached to correspondence) can be found in other files throughout the collection. (Though Baker was an avid photographer, his photos are not included in this collection.)

A group of negatives was added to the collection in June 1995 when they were sent to UT by the Senate Archivist. They have been kept in their original negative folders and sleeves because many of these have notes about the photographs on them.
