This week a rare stamp, The Inverted Jenny, surfaced. There are only 100 of these stamps in existence and each of them bears a hand written number on the reverse side of the stamp. The hallmark of the stamp is its flaw that the biplane on the front is printed upside down. This particular stamp, No. 49, has not been seen since 1918.
Like this stamp, we can only hope that the flawed political environment of 2018 will not be seen again for 100 years.
