The Bosch Post of the 1930s informed dealers about new products or technical developments, but also provided ideas for designing advertising materials. The Bosch Post of 1934 featured a window display for bicycle lamps, for example.
A bicycle equipped with Bosch lamps is shown traveling along a dark street in the moonlight as it frightens a pair of rabbits at the side of the road which then flee into the bushes.

In the 1950s, Bosch brought out an annual illustrated magazine for motorsport enthusiasts. It proudly reports on the successes achieved during the past racing season – with Bosch equipment featuring prominently, of course. From the very beginning, motor-racing gave Bosch the opportunity to test the quality of its products and parade them in front of thrilled spectators.
