Finding Missing Art (on the internet)

A few months back I found a site with some excellent drawings of soviet military hardware which I’ve been using since as wallpapers.

Today I found a further number of pictures, which are obviously from the same series, but while the original pictures I had found were desktop wallpaper sized these have been resized down.

(Check out the first row of drawings, those are the ones I mean)

I was wondering if anyone knows where I can find the larger versions of these pictures and/or any other sites with similar conceptual drawings?

Thanks a lot.

Actually, managed to stumble across them:

Love the fact that the Ukraine exchanged theirs to pay the gas bill!
