It begins, a new era of Superman Family coverage at the SBG, the Age of Krypto! Now, with both Reign of the Supermen and Snapshots of Jimmy Olsen, the idea was to showcase variants of those characters - those Supermen and Jimmies that had been transformed into ants/turtles, came from parallel worlds, were cast in live action productions, etc. That's not what I want to do with Krypto the Super-Dog. No, this is meant to be a full-on index series where each of the Kryptonian pup's adventures is chronicled, as much as possible in order of appearance, and maybe more besides.
Krypto was given life by Otto Binder, Curt Swan and Sy Barry in late 1954, the issue cover-dated March 1955, and the story titled "The Super-Dog from Krypton". The cover and splash page give the game away, but you never know. We're not technically in the Silver Age, but the Superman Family was already doing a lot of hoax stories already, and Superboy/man had been visited by many fakers before, people he only THOUGHT were from Krypton. Maybe there's a simple explanation for all this. So the first continuity appearance of Krypto is actually on page 2, as a dog about to be taken to the Smallville pound.
Alas, Adventure Comics didn't publish letters pages back then, but we can probably infer a good reaction from readers based on the fact Krypto would return just 4 issues later when such letters would technically have been published.
I'm not a dog person, but I AM a Krypto person. Who's with me? Those that are, see you next Saturday!
