A livejournal filled with comics based on 1950s clip art. Not "Get Your War On" story comics, but one off randoms like "Far Side" (but from a different sense of humor).

2020 Update: Youtube was founded the year after I wrote that post -- 2005 -- and has proved itself a great dumping ground for random old and foreign commercials. It's the place where everyone would look for such stuff now, but I couldn't believe a site accepting random video from the world would succeed when it launched. It is just too expensive to do that, which is perhaps why Youtube still has so few competitors: early product found an eager audience and other companies didn't want to emulate it until too late.
