Hey how ya doin? It's been a while, hasn't it?
Here are some interesting things I found today in "The Modern Home Physician, Illustrated" c.1942, which is a book I bought at a flea market years ago. I'm working on an illustration of robots and this stuff comes in handy. Sometime in the next couple of months I can post the how and why. (If you've been here a while, you might actually figure part of it out if you're super-observant. If you do, drop me an email and you'll get a prize.)
Also, if it interests you, I jumped on the late train and started doing that Instagram thing. If you're already there, which you probably are, follow me http://instagram.com/brianbiggs
