On this day back in 1918, the first airmail stamp was issued in the United States. Prior to this only parcel and postage stamps were used. This would also go on to become one of the most popular stamps of all time because it featured the Curtis Jenny Biplane on the front. Interestingly, 1 out of every 100 printed had the biplane upside down and would later be referred to as the “inverted Jenny”. IF you managed to come across one of these that was in mint condition, you may as well have hit the lottery because they have fetched almost $1 million at actions all over the world.
