1936 Gerhard Zucker Rocket Post, New York Exhibition

1936 Gerhard Zucker style rocket post. New York Stamp Exhibition Rocket Mail cover with 1934 New York Exhibition stamp but the year altered to 1936, and Rocket Post Experiment Flight overprint. These were not flown as Zucker was actually in jail back in Germany at the time, but his philatelic cover agent Karl Henning went ahead and produced the covers anyway as a show souvenir.
