Porsche's company logo is based on the coat of arms of the Free People's State of Württemberg of the former Weimar Germany, which had Stuttgart as its capital and became part of Baden-Württemberg after the political consolidation of West Germany in 1949.
The centre of the crest shows a black horse rampant, an expression both of forward thrusting power and a derivation of the Stuttgart city seal. Stuttgart, established in 950 as the stud farm of 'stuotgarten', has had horses in its coat of arms in varying designs since the 14th century. The crest has the outer contours of a shield with the word Porsche as the overarching signature.
The crest first appeared (on the steering wheel) in 1952 and on the bonnet from 1955
