My Uncle Charlie loved anything mechanical, particularly his cars. I had never seen this picture until we scanned the negative the other day. It comes from the days when cars had 'running boards' where you could step as you got in and out, and on which you could ride if you were daring. But Uncle Charlie seems to be driving the car from the running board. I can't think how he intended to put on the brakes.
I include two versions of the photo, digitally enhanced in different ways.
