re: Papua New Guinea revenue use on a boarding pass
I have seen quite a few of these. A number of countries use or have used Departure Tax Stamps. Most are quite attractive and with local themes. But, alas I have not been fortunate enough to find any for sale or trade. YET!
re: Papua New Guinea revenue use on a boarding pass
I have one like the example shown and another with a different style overprint on the same stamp. Scott #530 was issued in 1981 I have had both for over 20 years, so the example is probably fairly common.
