'Iron Gustav' during the visit of the Opel works in Russelsheim, 1928
On his return from Paris to Berlin, the 'Iron Gustav' visits the Opel works in Russelsheim. There he receives an Opel cap as a gift. His horse 'Grasmus' will be 'retired' after the return. The 'Iron Gustav', aka Gustav Hartmann, took with his cab a ride to Paris and back in 1928, in order to protest against the suppression of cabs by motorized taxis. The trip attracted huge attention in the public and made Hartmann a celebrity.
