I guess this thread is kind of the opposite of the "Visualize Rendered Content" thread...

I have a space on my wall that I'd love to fill with a nice piece of technical drawing... The more "real" the better.

My dream would be an old hand-drawn one from back in the times when hand-drawing was de-rigueur. When I was in school they cleaned out some storage room and found several old unclaimed assignments from drafting classes that they used to decorate the CAD computer lab (somewhat ironically?)

I've done a couple of searches, but they seem to turn up these "artificial" drawings patent drawings on fake vellum or this:

I'd really like something more "real", closer to this one: (except without the caliper etc).

Any of you guys have some cool-looking SW drawings with lots of detail etc. that aren't IP sensitive?

or if ​ has a basement or storage closet that needs cleaning out...
