First Underground Stamps from Szczecin 1970 Strikes
The stamp was created by the unknown author during the strikes in Szczecin's shipyard in 1970. According to Michał Guć, the strikes of Szczecin's shipyard workers started a wave of underground postage activities. The stamp was created in the POLMO plants and it comes from a pre-Solidarity era. In contrast to the later stamps of 1980s, the item defines itself as "post of the economic strike".
