The problem is, it's not just making a continuity error in an unrelated comic book . . . it's a series that was revisiting aspects of the Golden Age, so one would think they'd get those details correct. Yes, they've taken liberties and aren't slavishly redoing the old JSA, but this was a clumsy mistake involving something they should have gotten right since they already had the Tyler name in the company.
(Whatever . . . I gave up on the book for other reasons. As I said previously, hopefully they won't put the same nitwits in charge of editing/overseeing the relaunched version.)
