These striking period door handles were designed for the administrative offices of the giant I.G. Farben paint factory in Frankfurt.
The building, completed in 1931, was the work of the architect, painter and set designer Hans Poelzig.
One of the progenitors of the Modern Movement, Poelzig participated in the first major International Style project, the 1927 Die Wohnung expo.
The event saw the construction of an entire estate of modernist dwellings in the elevated Weissenhof suburb of Stuttgart.
Poelzig contributed a prototype single family house alongside Le Corbusier, Mies van der Rohe, Gropius and Behrens among others.
His imposing I.G. Farben building still stands and has become the centrepiece of the Goethe University campus in Frankfurt. Poelzig died in 1936, aged 67.
I suspect that these nickel-plated bathroom door handles are probably later production, possibly late 1940s.
