***EXTRA: Bob Kane Swipe Spotted***

A reader caught this when I didn't. This panel from a Dec, 1938 RUSTY & HIS PALS story by Bob Kane was lifted nearly intact by Kane as a panel for the debut BAT-MAN story 6 months later in DETECTIVE! Since much of that story has been documented as Alex Raymond swipes, I'm wondering if this panel, too, might have originally come from FLASH GORDON! Thanks Silver Fox!
