Scrapbook #1: Photograph album presented to Mama holds pictures of Leslie Mann and his family, and places they, or he alone, traveled to (Washington, D.C., Boston, MA, Seattle). The Scrapbook is black with a hard canvas cover and thick, black paper pages. "Photographs" is written on the front cover. At the beginning of the scrapbook is a written message from Leslie Mann and his wife (Jessie), gifting the photograph scrapbook to his mother for her birthday on August 31st, 1914. The measage reads, "Presented to Mama on her Birthday, August 31, 1914. May this book bring foond recollections of the days bone by and express our love. Wishing you many, may years of love, health and happiness. Jessie and Leslie." The photographs seem to span from March to August of 1914. They are labeled in cursive with the date it was taken, where it was taken, and who is in the photograph. Where writing is hard to read on the photograph someone has placed a post-it note with the text rewritten.

The scrapbook contains a program for the Baseball Tournament at the New England States Championship Eastern States Exposition in 1931, newspaper and magazine articles about Leslie Mann's baseball career and work for the U.S.A. Olympic Team and U.S.O. in baseball from between 1917-1945 (one article is in Spanish), a transcript of an interview with Frank Bull, Bill Schroeder, and Leslie Mann, and more newspaper articles about Mann's work as a baseball scout and his legacy from ca. 1949-1959.
