Around 1914, Lucian Bernhard was commissioned by Bosch to design the advertising poster “Bosch Plug.” Bernhard kept it simple and as a result, this now classic design communicates dynamism and power. Bosch used the igniting spark plug image produced by Bernhard not only for advertising posters, but also for the spark plug packaging. The metal plate design shown here, produced around 1930 is printed on a black tee. Sizes M-2XL.
