In Herman Herst, Jr.'s Fun and Profit in Stamp Collecting, he writes, "An approval dealer named George Wentz conceived of a United States-to-Mexico rocket flight across the Rio Grande where it was probably no more than a trickle. For years he offered examples of this flown cover as approval premiums to encourage collectors to buy his wares." . Suggested Bid $250-350 (Image)
