1971 strike mail

Great Britain experienced a postal workers strike from 20 January 1971 to 8 March. Many private posts were established for local, national and international service in the meantime, many issuing their own stamps. These were both authorized and unauthorized. Stamps exist for both genuine and fake services.

Designs range from plain labels and rubber type obtained from stationery stores to original artwork to surcharged color advertising labels and foreign postage stamps. Without genuine covers or parcel fronts, it is often impossible to tell legitimate carriers from bogus ones.
