This is a vintage 1975 Hang Glider enthusiast magazine publication reference book Lot of 2 different that I found at a Seattle area estate sale. It is a Nov. & Dec., 1975 Lot of 2 GROUND SKIMMER Magazines (see pictures). They are in lightly used condition, complete, no missing pages or damage (see pictures). This vintage 1975 HANG GLIDING / Ground Skimmer Magazine Lot of 2 comes as shown in the pictures. Should be of interest to older hang glider publications-reference books-accessories-memorabilia & vintage 1970s Hang Gliding / Soaring / Wings Unlimited / Ground Skimmer related collectors. Take a look at the pictures & e-mail me with questions. Buyer pays $4.90 USA shipping. I will combine the shipping for multiple auction buyers.
