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.
Does anyone have any information regarding how stamps have been used as a sign of protest. This is specifically in regard of placing a stamp upside down as is illustrated in the attached image of a Hindenburg medallion on an envelope posted from Strasbourg. Was this a deliberate act, and if so could it have repercussions on the sender? Thank you.
