I will carry on with the Phnom Penh postmark series later. This time let's have something light.
Here is a set of 1999 Afghanistan Cacti 6v:
If you are a collector of Cambodia, you will find the stamp design very familiar, it is the virtually identical to the 1990 Cacti 7v set:
This is not the first time when two countries coincidentally share the same design without piror arrangement, but it is a first for Cambodia.
Both sets were produced by COPREFIL, however as stated in UPU International Bureau Circular #345 of 21st August 2000, from 1990 on the Kabul administration did not commission any printers to produce stamps, so the Afghanistan set is illegal. Afghanistan issued stamps again in 2002.
