Here's a terrific ad from the early days of Timely Comics. It's not terribly interesting from a style point of view, but rather as a piece of history. First, note the announcement for the upcoming All-Aces Comics. Never heard of it? Well, nobody ever saw it. I believe that this was the original working title for All-Winners Squad. Also note the 'Imitators Beware' section, which is a stern warning to other publishers cranking out patriotic heroes. Timely is conveniently ignoring the fact that they ripped off MLJ's The Shield. Ain't history fun?
