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.
A friend of mine, who does not collect German stamps, has found in his wide inherited collection a copy of Heligoland SG12 or M17.
He wants to check if it is genuine. I have no idea can anybody help please? Many thanks.
