Most of the letters are written to Walker from Edward John Moreton Drax Plunkett, 18th Baron Dunsany, 1878-1957, playwright. Correspondents include Lady Beatrice (Child- Villiers) Dunsany, Benjamin F. Roeder, Booth Tarkington, Susanah (Keifer) Robinson Tarkington, and Stuart Walker.

The letters from both Lord and Lady Dunsany relate their various activities, including Lord Dunsany's writings and his army service in the war. Those from the Tarkingtons all date from the last quarter of 1917 and most often involve Walker's staging of Booth Tarkington's Seventeen. The carbons or drafts of Stuart Walker's letters that are present are all addressed to either Lord or Lady Dunsany. A few of the letters exchanged between Walker and Lord Dunsany during 1916 have been published, in whole or in part, in Bierstadt, Edward Hale, Dunsany the dramatist. Boston, Little Brown, and Company, 1917, p. 133-168 (Main PR6007.U7 Z5).

Walker's writings present in the collection are "Six who pass while the lentils boil; a play in one act"; and "Three vignettes; three thumbnail sketches." The latter item consists of two short plays: "The medicine show" and "The very naked boy." A folder of miscellaneous poems and fragments completes the collection.
