No, not really.
Actually, it wasn't a "publishing window" of 1940 - 1998 as much as using that time frame in reference to who had joined the Justice Society of America by then. The "1998" endpoint was only because 1999 was when the JSA series was launched and that added many new members to the team.
Many of those later members are covered in a separate thread, JSA/Justice Society of America Poll: favorite members (from 1999-2008).
