On October 2, 1933, one of my favorite US stamps was issued in New York
City – #C18. The stamp had a total of five First Days of Issue – one at
each city the Graf Zeppelin stopped at from New York to Chicago. Today, stamps have only one First Day of Issue, so this was quite unusual! .
Only about 32,000 of the 324,070 #C18s stamps were sold. That remaining 90%
of the Post Office Department’s stock was destroyed! That makes #C18
scarce today in any condition. Get the stamp plus genuine covers flown
aboard the Graf Zeppelin in your collection today…
