Thanks to IMCDB for presenting pictures of cars in more lifelike situations. I have plenty of carbooks, but most photographs are staged and show cars from only one viewpoint. I used the pictures on the site as inspiration for a steampunk-comic set in the 1930ies. I modified the cars, but most of the drawn cars are based on real vehicles. So happy guessing:
