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.
My collection has just taken off in (yet!) another direction, this time to the issues of German Colonies and POs overseas.
I have bought several postal stationery items and wondered if these are listed anywhere.
Any guidance would be welcome
