I got hold of > 300 different types of card calendars (a typical giveaway in Hungary in the 70ies/80ies).
will scan and publish them here.
it is amazing that no matter what crappy or utterly strange product you had, you had to publish a card calendar :-)
it was also treated sometimes as an "educational medium". it was common among people to collect them, just as stamps, coloured paper napkins, box of matches, etc...
