"Rogue Attack!" from Flash vol.1 #174 (DC, 1967) by John Broome, Carmine Infantino and Sid Greene
I love the Flash's powers, and he's inherently, regardless of who's behind the mask, one of my favorite DC characters because of it. And my first Flash WAS Barry, back in the days when the only superhero comics I could read were black and white French translations in frankly random-ordered "JUMBO" books. The one where Mirror Master's giant hand comes at the Flash? That was my first Flash comic. But I desperately dislike Carmine Infantino's art. I can't help it. And since he drew a LOT of Flash, from the first stories right up to the end of the book, it turns Barry's Silver and Bronze adventures into a really difficult read for me.
