Speed in 1950

I did warn you that we were in for a bit of a vintage graphics binge: which is really because I know what I've been acquiring recently, including these great images by Kenneth M Sibley from c.1950 that were published in The Wonder Book of Speed, a book free entirely from all modern considerations of things such as the avoidance of hubris, environmental concern, and any limitations on the notion of 'progress' at all.
