Very, very nice! I especially like the last two pieces commemorating the centenary of Portugese India. I have a card from Portugal featuring this same event. I wonder if there are similar ones from other Portugese colonies.
I came across this nice postal card from the West German side. Issued in 1980 as a special printed card (I think) celebrating the Zeppelin. Front and back shown. (My German private print catalog stops at 1980 or I would have a number for you).
