6/7/71 and the cover is Al Unser and Pete Revson.  Unser winning the Indy 500.  In an Indy 500 of many calamities, defending champ Al Unser drove an aptly named car to victory.  In a stunning upset, Great Britain won the Walker Cup from the US for only the second time in half a century.  Feature is Himalayan Trek or Treat.  Now you can trek, a euphemism for walking, or limping, up and down through steep, stony, beautiful Nepal.  Nice copy, see photo of the cover.  In the US; combine with other auctions to save on shipping.
