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 used to collect the German colonies but have sold all of my stamps and post cards. I still have about 20 reference books mostly in German. I would like to sell them also and am looking for interested collectors or auction houses. If you need titles, I can send a list. I live in Toronto Canada.
