Remember the time Superman gave Jimmy Circe's magic wand for his trophy room? And then Jimmy grabbed it to play marching band for lack of a proper baton? And it gave him the power to command animals and he let it get to his head? And it got him into trouble? Sounds like an ordinary Tuesday in the Silver Age.
Well, the page above is Krypto's contribution to that story. He shows up on the last page, is commanded to help Jimmy (like he wouldn't have), grabs the wand in his jaws thinking it's just a stick, and disintegrates it with friction because he's flying so fast. The writer missed a trick. He should have had Jimmy tell Krypto to save him, "quick!" which would have created some irony there. Instead, it's just Krypto destroying precious archaeological artifacts, as normal.
Did Indiana Jones never meet Superman? Cuz someone needs to tell him those things belong in a museum!
