In this previous post, I showed my first example of of the bogus 1921 Retardo Overprints that appeared on Colombian stamps due to the efforts of an enterprising postal clerk.
I have since added 2 more examples to my collection.
The first is a Retardo 1921 Overprint on Scott #363. This is overprint Type III (see previous post)
Type III has a different R than Types I and II.
The second new example I have is overprinted: “Retardo” vertically without the “1921”. According to the article, these were done in 1919 and were overprinted using a typewriter:
initially 2c red stamps of 1908 and of 1917 were surcharged by Remington typewriter. These were issued in 1919 and will be covered by a future article.
Now I can’t fully tell if this was done by a typewriter or not, but the overprint is blue in color.
