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.
Is it true that the Bavarian Prince Luitpold issue of 1911 were the first stamps ever to be produced by the process of photolithography, and that the Bavaria 1914 Ludwig III issue were the first stamps ever produced by photogravure? Could anyone point to a good authority on these issues? Many thanks.
