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.
The shown bellow is 1R stamp issued by Geman-Baltic committe in St.Petersburg. Can you let me know exact date of the stamp issue? Also, if there are any of other stamps of the sort and if anything is known as the post was operating?
