A new simplified type, the British Visitor's Passport, was introduced in 1961. It was a single sheet of cardboard, folded in three so as to consist of six pages the same size as those of a regular passport, and was valid for one year. It was obtainable for many years from Employment Exchanges, as agents of the Passport Office, and later from a Post Office. It was accepted for travel by most west European countries (excluding surface travel to West Berlin), but was dropped in 1995 since it did not meet new security standards. A cancelled passport, which was returned to the bearer, had its top-right corner cut off, which had the effect of removing a corner from every page.
