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 wonder if anyone can point me to an accessible sources of information about these subjects. I have had a quick look on the library pages but couldn't see any general source.
I have a reasonable selection of stamps etc pre and post WW2 but would like to give a talk to my local society.
