Official publication of the Soaring Society of America. Each issue 8x11", 16 pages. January 1937 issues is Vol 1, No.1 with a 8 page insert on the history of soaring by the society founder, Warren Eaton (this is an important issue). Oct 1937 and Sep 1938 issues are each 16 pages and, unfortunately have some small clipped areas on a few pages. Else wise good condition.
