I'm pretty sure the characters never met during the Golden Age. But what if they did?? Could GA really impress BC with his great Arrow Car?? BC doesn't seem to be taking the bait. She's used to attention from blond guys in green. Yes, I'm talkin' 'bout you Johnny Thunder!!!
Mark Heike was one of the artists in the AC Comics stable that almost singlehandedly dragged good girl art (or GGA as they say) kicking and screaming (of course) into the 1990's. This was before DC and Marvel really started taking advantage (double entendre alert) of their heroines.

It seems there was such a thing as an Arrow Car.
Black Canary was created by Robert Kanigher and Carmine Infantino.
Green Arrow was created by Mort Weisinger and George Papp.
