So, here's something totally different. This was an early (1941) experiment in digest-size comics, put out by Harvey Comics (who went on to publish some of the more outrageous horror comics of the 50s). Speed Comics was a regular-size comic from issues #1-13, but became a 100-page "pocket comic" from issues #14-16... here's the first of those issues. Note the cover's war theme, several months before America officially entered the war.
Harvey simultaneously launched a title called "Pocket Comics" which ran 4 issues before folding. The story in some of the earlier Overstreet Guides is that this 'pocket' format flopped because kids found the digests very easy to steal, depriving vendors of their dimes... don't know for sure if that's truth or urban legend, but I find it believable.
