Some notes:
Interesting to see the variety of genres - superhero, western, mystery and sci fi, funny animal - and Buzzy!
Curiously, this issue begins with a single page filler - an inauspicious opening gambit.
There are two exclamation marks in the title Rex of the Fighting Seventh! Cavalry!. This not an error on my part.
This issue does not appear to have the extensive art modifications we've come to expect from such issues, however there are two notable exceptions.
Firstly, for some reason, the title of The Signalman of Crime has been modified - compare the splash page in Century #24 with a scan of the page from Batman #112:
Secondly, as mentioned at the outset, the cover image has minor touchups, which I believe may have been done by none other than Hart Amos. Many years ago I was contacted by a member of his family via this blog, and one of the things I received via email was a scan of the cover proof to Century #24 which was in the family's possession. Indeed, I believe this is the image which has been on AusReprints for many years (James can correct me if I am mistaken - unfortunately I can't verify this as my computer at the time died and I lost all such files and contact details).
Ironically, Century #24 turned out to be the last issue I needed to complete my run of this series. And who would have thought that after eluding me for so many years, it would be sourced at the same time as Mighty #29, which completed my collection of that series. That's just how things roll in the Junkyard.
Thanks to Mark Cannon and Mark Muller for supplying me with scans of House of Mystery #70.
