Passport booklets (1921–1993)
As with many contemporary travel documents worldwide, details were handwritten into the passport and (as of 1955) included: number, holder's name, "accompanied by his wife" and her maiden name, "and" (number) "children", national status. For both bearer and wife: profession, place and date of birth, country of residence, height, eye and hair colour, special peculiarities, signature and photograph. Names, birth dates, and sexes of children, list of countries for which valid, issue place and date, expiry date, a page for renewals and, at the back, details of the amount of foreign exchange for travel expenses (a limited amount of sterling, typically £50 but increasing with inflation, could be taken out of the country).[25]
If details and photograph of a man's wife and details of children were entered (this was not compulsory), the passport could be used by the bearer, wife, and children under 16, if together; separate passports were required for the wife or children to travel independently.
I am 99% sure that my children did not have separate passports in 1969 and possibly 1974. I think they travelled on my husband's UK passport.
Photographs, if used, did not have very strict regulation as they do currently. I have seen a passport which used the person's photo which had been cut out of a family group photo.
So there may have been no need for "Ure Beatrice WARD" (or whoever she was!) to have a photo in the passport.
