Generally speaking there's not much to be said these days for clip art. Some folks do it quite well, of course, but usually it's nothing to get excited about.

That is not the case, however, with the images in this vintage clip art collection from Bart & Co. Maybe it's just that the passage of time tends to make things feel more interesting than they were when they were new, but whatever – this stuff is just cool. 

Enjoy.

Oh, and, hat tip to Khoi Vinh at Subtraction for originally discovering these.
