Gas Saving Ad – Mechanix Illustrated, Vol 1, April 1942


Feature Image

My grandfather on my dad’s side was a packrat. Not a hoarder, but a packrat. He kept everything! He didn’t just keep things, though; he cataloged them. When he would buy a bottle of hand soap, for instance, he would put a piece of masking tape on the front of the bottle with the date of purchase, purchase price, and the store where it was purchased. I don’t think he ever threw away a magazine, and he subscribed to many. Popular Mechanics, Popular Science, several now-defunct magazines, newspapers , and the subject of this particular series, Mechanix Illustrated (which he labeled Mechanics Illustrated for some reason).



Mechanix Illustrated was a magazine published from 1928 through 2001. Grandpa bound the magazines in large books containing about 6 magazines each. His personal collection runs from 1942 through 1971. Some of the WWII articles are fascinating! I hope you enjoy seeing some of the articles and ads that pertain to vehicles of the time!

  1. Nice job, Garan. Grandpa would be pleased. Wonder how many Vacu-matics were ever sold? Was that from a 1942 mag?
