My old friend and general mensch-about-town Ken sent me a great website: Retropolis Transit Authority, a look into the future that never was. As Ken said, "Space cadets, mad geniuses, rocketeers, space pirates, old-fashioned death rays, streamlined blimps, and personal jet packs--everything you could desire in yesterday's future!"
They sell t-shirts and other merchandise. I'm copying one example to show you what it's like, but there are dozens of other things that I want you to see, so go look at the site and possibly buy something. The artist, Bradley W. Schenck, has done a wonderful job. Go look!
