The last picture of this strip used to be the epicentre of my desperation for quite a while. Having become a fan of Beetles I wanted to make the car look as credible as possible. And so I used photos and even a little model car. The latter had some sort of knob on the inside of the back side. Against my own belief that Beetles don’t have movable rear windows, I trusted that model and drew this picture. Only to find out, that I was right, the model was crap (or at least, the knob wasn’t a knob at all), and so was this picture.
However, I found a – flimsy but satisfying – explanation for the window later on in the story. You’ll see.
