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 recently started collecting 3rd Reich Postal stationary & History. Are there any catalogues, along the lines of Michel(Cat No's, values etc.), for either postmarks or postcards?
