I've often thought about the issue the author brings up. I'm not sure what the case is now, but when I was a kid (15 or so years ago), cartoons were full of anachronistic items that I probably never would have seen otherwise. Generally when you farther back, items become more differentiated and easily identifiable. A lot of these cross over with computer icons - telephones, antennas, alarm clocks. I really wish I could find a good listing for this type of thing, but my google fu is failing me.
