A few years ago in our country there was a popular seria of cards with Damavik by Alena Uglyanitca.
And some of those card were special - if a frame on the card is not completed than there is the other card that matches it - such kind of card puzzle. But each of the cards is a full-sized postcard.
two matching cards
four matching cards
- I wonder if you have cards seria in your country with same characteristic. Could you please share it.
- Also imagine please that you have several cards with such characteristic and answer:
- Would you send them one per recipient or you’ll send at least two matching cards?
- Would you inform your recipient about this characteristic of cards?
Update from 03/03/2021: similar cards used to be named - INSTALLMENT, INSTALLMENT Puzzle cards, INSTALLMENT postcard sets
