German Ministerialpass Ruth Doerner
This passport type is pretty rare. I saw only 2-3 within the last 15+ years. This Ministerialpass was issued during the Weimar Republic period in 1925, was twice renewed and valid until 1930. The size of this type was significantly larger than a standard passport of these days. Of the 32 pages, five have entries with diplomatic visas from the Netherlands, Belgium, Switzerland, and the UK.
Furthermore, there are two private documents of her related to her university in Germany and the USA. Ruth was born in London and was the daughter of the German consul in Haag, Netherlands.
