Note: This record represents the front cover or jacket illustration of the novel in the August 1920 first printing of its 1st ed. (The Story of Doctor Dolittle: Being the History of his Peculiar Life at Home and Astonishing Adventures in Foreign Parts, Philadelphia: Stokes).   The illustration is unknown (April 2018) because online dealers and collectors, those who do provide images, give incomplete or inconsistent information. Wikipedia provides a cover image, simply as "first edition", probably relying on a single dealer at ABEbooks. Another dealer provides an image that appears to match, with description "Orange boards with faded blue lettering on spine and front, line drawings of sea creatures in blue paste down color picture on front." That paste-down illustration is "The Farewell Feast", which is the frontispiece illustration in some eds/printings.   That work is known to be used on the front cover and as frontispiece of the November 1923 15th printing (front cover) (viewed at HathiTrust). It is also displayed as the front jacket of the British "second issue 1924" at Hugh Lofting First Editions.
