Very nice: the stamps I had purchased just 11 days ago from my seller in Spain, landed in my mailbox tonight. The mailman should be commended for still doing the rounds at 8 at night.
This time the mailing envelope has the dreaded computer-processed postage label on. (Some philatelists don’t mind: they collect even these machine-generated labels).
SWA on the stamps: South West Africa, Namibia’s name until independence in 1990.
RSA on the stamps: Republic of South Africa, South Africa’s official name since 1961 (before 1961 the country went by the Union of South Africa, and like Canada, Australia and New Zealand, it was a self-governing dominion of the British Empire).
