Issued on March 20, 1923, the 30-cent stamp featured a buffalo that resembled the 'buffalo nickel' in circulation at the time. It is the only stamp in the series on which a ribbon does not appear under the vignette. Clair Aubrey Huston chose a 1901 drawing of a bison by Charles R. Knight as the basis for the vignette. Knight reported that he completed his drawing by observing a bison at the Zoological Park in Washington, District of Columbia. Louis Schofield engraved the vignette. Edward M Hall and Joachim C. Benzing engraved the frame. Issued at Washington, D.C., and printed on the flat plate press, the stamp was subsequently printed on the Stickney rotary press.
