Spain was the special guest on the national exhibition CROATICA 2015 (31st March – 4th April) in Zagreb (Croatia). There was a joint issue of the Croatian and the Spanish Post (traditional embroidery). Also exhibits from other invited countries Austria, Czech Republic, Hungary, Portugal, Slovakia and Slovenia.
In total 86 exhibits of which 17 in thematic philately class (4 from Slovenia, 1 from Slovakia and 12 from Croatia). More than half of them (9) were one frame exhibits. In this class only diploma, bronze, silver bronze and silver medals were attributed to the exhibitors, so unfortunately no exhibit that has been found strong enough to compete at international level.
