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 have acquired some german postal stationery cards which contain a few Rohrpost-Karten. I know this relates to Pneumatic mail. Can anyone please tell me where and when and how this service came into operation. Thanks in anticipation.
