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 have several stamps from Hassendorf, Montgomery and Seedorf Displaced Persons Camps for Lithuanians.
I also have 3 of the Hanau Estonian Camp issue.
I have been unable to find any information about the camps for Baltic citizens using the internet.
