"Horace Walpole's Correspondence Edited by Mr. Wilmarth S. Lewis" was compiled by Annie Jennings to document the first volume of the Yale Walpole correspondence series. It includes the series prospectus, and other ephemera, typescript copies of Wyndham Ketton-Cremer's poem on the publication, newspaper clippings related to the volume, copies of an award notification letter from the American Institute of Graphic Arts, and typescript copies of C. B. Tinker's citation when Yale bestowed Lewis's honorary degree.
