The year 2014 marked the 50th anniversary of the first year of operation of the Germany & Colonies Philatelic Society following the amalgamation of the Germany & Colonies Stamp Club (established 1947) and the Stockton German Study Group (1960).
The G&CPS celebrated its inaugural year in 1964 with the first Germania Posta philatelic exhibition held in Stockton.
I've just bought a load of German covers etc, one of which is a card with the above stamp tied with a special postmark commemorating Koch's 100th Birthday, dated 11.12.1943. Michel says that it was given this date as a favour to match with his Birthday although the stamp was not actually issued until 25.1.44. My query is does my card count as an FDC?
