I have added another serial numbered card from the Czech Republic to my collection. The card in question is a 1998-99 OFS Hidden Treasures with a serial number of 1/3. The player featured is Angel Nikolov.
I have at last acquired the only Angel Nikolov card from a Czech league set that was missing from my collection. The card in question is number 154 from the 1999-2000 OFS set.
