The biplane shown in the picture was the type of plane chosen to carry the very first air mails in the U.S. Something designed to commemorate this selection is now extremely precious and famous. What?Answer: This is the Curtis Jenny biplane that was the plane of choice for the first air mails. To commemorate the event, the airmail stamps were supposed to carry the picture of the plane. However, the plane was printed upside down in the stamps as a mistake. The mistake was rectified very soon and there are very few "Inverted Jenny"s in existence making them among the rarest and most priced stamps. and are now valued at nearly a million dollars. Srivats, Iam, Shweta, Avi and Swapnaa got it. Well done.
