From a San Francisco flea market comes a little book of sketches of Chicago life from more than 90 years ago.  Thanks to Mel Kadel and Travis Millard, you can see them all here and wonder who produced these vivid little cartoons.

Then you can read through the comments and watch the hivemind at work, learning why someone would bind up a book with only the first few pages actually printed (leaving great sketching space), and that the sketcher may have been Andy Hettinger, an early Chicago animator who died young. Can anyone else continue the detective work?
