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 am in possession of SG30 & 31 the high value stamps in the Saar 1920 overprinted Bavaria set.
On the back there is typed in very small print
" Aufdruckflasche "which is suggesting that they are forgeries. Is this a common occurrence or do I need to dig further,
Many thanks
