I've managed to acquire these 9 SAAF commemorative postcard covers, all in pristine condition for the princely sum of $9.80! Scary to think how much postage costs these days, looking at the stamps.
As you can see they have artwork on the front and then on the rear it tells you what number in the series this envelope is, plus a little story on what aircraft it flew on and when. Inside the envelope is a brief history in Afrikaans and English about what the envelope is commemorating. I'll only type out the English versions.
