Refugee Relief stamp

I should note that even though we do see the "RA" prefix for postal tax stamps in the Scott catalog for a lot of countries, Scott does not have good coverage. Some major countries have many postal tax stamps that are not Scott listed, particularly Turkey and the Balkans. It's not just a case of different local overprint varieties such as for India.

Turkey is one of those countries where you might easily encounter a postal tax stamp that is not Scott listed. You will find very close/similar/identical designs, but for a color or value that is not Scott listed. Often what happens is those postal tax stamps were only required for a very short period of time (e.g., a day, a week). Scott has a tendency to skip over those, and yet still list some here and there!?! No apparent rhyme or reason. Again, Turkey is a good example. They will list some postal tax stamps that were only obligatory for a couple of weeks, but not others.
