Palo Alto, California: Yvor Winters, 1929-1930.
Four issues. May 1929 - February 1930 complete. Mimeographed sheets in stapled mimeographed wrappers. Chipping to the yapped edges, and the front wrap of the November, 1929 issue is detached but present, a good or better copy. A complete set of this short-lived but influential California literary quarterly edited by Winters -- along with Janet Lewis, and Howard Baker, who were the principle contributors -- for his classes at Stanford in 1929 and early 1930. Caroline Gordon and Katherine Anne Porter also contributed. The Gyroscope is considered one of the earliest, if not the earliest, mimeograph literary magazines. An extremely fragile format with a limited print run that never grew beyond 180 subscribers, many of those the top literary figures of the day. Finding individual issues is quite difficult and putting together a complete set doubly so. The grandfather of the mimeograph revolution.
