From Google Translate:
On the front:
It was not, but only in South Bohemia could be…
Magical South Bohemia, Map Carp James (?)
On the back:
Collectors of postcards with carp, James will get in a fabulous office for every 10 cards slosovatelny coupon. On the autumnal fairy tale in Ceske Budejovichich will be drawn on a collector who will receive a mountain bike brand Anlen.
I’m not sure what this all means, but I am sure thankful for Google Translate, which at least gives me a chance to try to understand 🙂 I am guessing that the fish all over this card is a carp named James 🙂
