Brian Cronin at Comics Should Be Good just mused about the many covers of World’s Finest Comics from the 1940s which show Robin, Batman, and Superman basically goofing off: “I think it is fun if you just pretend that all of these covers happened on one really amazing day.”
The weekly Robin discussed those covers back here: “Robin appears delighted at having the two coolest older brothers ever.”
Is this one of the many examples of Robin slipping and falling from the first three decades of Batman comics? If so, Batman and Superman are blasé about it. Perhaps they’ve seen it too many times before. “Oh, there goes the ‘Boy Wonder’ again. I bet you wonder, Batman, when he’ll get past adolescent awkwardness.” “You’re lucky you don’t have to watch him chase after crooks, Superman.”
Then again, Robin himself appears to be smiling. Though he’s let go of a perfectly good mountain-climbing axe, he may well have flung himself off the cliff for fun. “Flying Graysons ruuuuule!” After all, he knows he’s got two expert catchers.
