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 trying to get hold of an envelope with the Gely Tin Toy Manufacturers on the cover from the 1920s-30s period.
Are there special dealers who cover German commercial covers, or do they appear at certain types of auctions?
