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.
Can anyone shed any light on this 1948 -1- Stamp. I found it in a mixed lot of German stamps bought off eBay. I've done a google image search to avail and scoured my catalogues. No watermarks visible, simply the year 1948 and the 1 above that, not even a monetary symbol. Could it be a unofficial cinderella stamp?
