Old and New

I was looking up an old political cartoon that I'd intended to post a month or two ago, and finally found it here. That led me to remember the outstanding work that Cox and Forkum do regularly, so I went to check out what they've been up to lately, and found this gem.

If you can tell me, specifically, what it represents and why it's funny, and your name isn't Anachronism or Sneaky Pete, I might just send you a copy of the archive CD. Do you dare accept my challenge?
