The strike in the public transport is lasting in Paris because of the rugby world cup final, a four day holliday, opportunism of the announce of a presidential divorce, and others things that make journalists and French people so lunatic. I take advantage and continue on strike stamps.
In January and February 2007, in the United Kingdom, a postal strike lasted so long that the British government suspended his postal monopoly. The decision permitted to legalize private citizens and organizations to transport mail (some for lucrative philatelic reasons).
If it can be of use for some one : a cover dealer of the carré Marigny, near the Champs-Élysées avenue, is selling covers from the 1971 strike. They are inside a box of 1,50 € covers. They wear a two-flag label (the Union Jack and the one of the country of destination) and a text explaining the legality of the transport. On the cover, there is a cancelled stamp of the country of arrival too.
