Some weeks ago the SFF (Sveriges Filatelist-Förbund or Swedish Philatelist Federation) asked his members to congratulate Gunnar Dahlvig for his 90th anniversary (born 1929, September 22). He is still very active as exhibitor, earlier in thematic philately class, but now as a defender of the open class (in opposition to open philately class).
Gunnar Dahlvig is very known amongst thematic philatelists. He was the vice president of the FIP Thematic Philately Commission from 1992 until 2000. His most known thematic philately exhibit is Tennis – a very old modern sport (with a large vermeil medal on Bangkok 2003). Earlier he also had an exhibit The Vikings that received a gold medal on Philexfrance 1999. He now exhibits in open class with Viking Time, also on the next national exhibition in Denmark – Copenhagen 2019 (18-20 October).
