We all know the beautiful Croatian cards with chip, but the first cards, in use from 1991 to 1994, were magnetic cards supplied by GPT. The first one had the Croatian colors on white background, and just 5,000 printed with 1CROA control.
The same picture was reprinted later with 2CROA control (25,000 issued) and in large quantity with 3CROA control (301,436).
