Further to my post on 30th April 2013, here is another souvenir card from the International Philatelic Exhibition STOCKHOLMIA86 held in Stockholm Sweden, from August 28 to September 7, 1986.
The stamp on this card is dedicated to engravers of stamps, and is one of four issued in 1984 to popularise Stamp Collecting and as an advertisement for STOCKHOLMIA86.
Thank you Merja.
