Never see her draw like this. Anyone know what issues/series this is from?
It may be from this period. But I can't confirm or deny it at this point.
Late period JSA, just before Infinite Crisis when PG got reconnected back to being from Krypton-2. In other words, while she was still technically on the Atlantean thing. The Hawk man/Black Adam, IIRC, or rather its prelude.
As for the style, that was pre-Connor, amidst an era where Alex Ross's bodybuilder Power Woman from Kingdom Come was still influencing artists. In other words, while that's a bit extreme, it's hardly unique. By the time Connor came around and set the new standard for PG's look, thus saving her for fans, she'd already been brought back around to that end of the spectrum to a large extent, and Connor just formalized the look and tweaked the costume a bit, while toning down the muscles, (though not the bust size as much).
