I long for the days before we, as a culture, harnessed the power of subliminal messages.
This offering, designed to encourage the conservation of precious fuel for the war effort, could not be more liminal. It's the advertising equivalent of printing your message on a length of 2x4 and wallopping your intended audience with it in the face.
I love how sad Hitler looks- he clearly has so many other things to do! "Ich told you to take the 508! Das highway is always bottlenecked at rush hour! Scheisse!"
