Aviation instructional program promoted by Radio Station WLW in Cincinnati and Colonel Weir Cook, 94th Aero Squadron. Apparently young aspiring pilots joined as a member and then (irregularly) received lessons through the mail by sending in labels from cans of Pennant Syrup. Presented here is an original membership booklet, the first page of which is a membership document to Paul George Denny. Following is a glossary of terms and Lesson No. 1. Included is the original mailing envelope. Very good condition.
