Shortly after the Second World War, communist influence grew in Romania.
King Michael, king of the Romanians was under high pressure in his own country, by members of the Communist Party.
In 1947 he was forced to abdicate, when Stalin's troups were there end of december 1947.
After King Michael left, Romania became a Soviet satelite state of the former USSR
In 1956 Romania was therfor still under communist leadership.
Not everyone was happy about that, and the gouvernment in-exile issued some stamps, similar to the ones issued by the European Community for Carbon and Steel.
The tower that is supposed to symbolise the construction of Europe, is tumbling down on these stamps.
Also the text underneath the building is a cry for help to the western world, to help Romania (from the communist influence).
These 'stamps' are not official - to be considered as propaganda, or cinderellas.
But it's a nice addition to the 1956 set of CEPT stamps.
