COLOMBIA Air Post
1919 First Experimental Air Mail Flight June 18, 1919.
200 copies of a 1917 centavo stamps were overprinted.
They were unofficially overprinted by typography
This was executed in horizontal strips of ten, which were severed with a guillotine knife, causing horizontal perforations to have a "cut" appearance.
The plates also produced 10 different positions which can be identified.
Of the total stamps issued, 160 were used on covers on the special flight.

| Original issue |
Forgeries are VERY plentiful ranging from crude to very good
One way to determine them is by the key features of the 10 types.
This can be difficult based on the inking differences.

| Typical forgery (date inclined) |

| Original & only postmark |
