I don't think that's supposed to be 'The JLA'... I think it's just 'Earth 1985'. John Stewart wasn't on that league... but I don't actually remember Supergirl or Batgirl being members either and Zatanna had given up the fishnets by that point hadn't she? Mostly the picture doesn't actually label it as the League.
