My observations was there would be 2 similar logos
in the same pass ^^.
Joker didn'd need a top hat. The top hat used by
Arsene isn't the same hat, because it is much more disproportionate. In
Utlimate,
Joker don't have a hat. If
Layton was planned from the start in the past, why would
Nintendo have given a top hat in the
Joker logo in the same pass, top hat which is THE
Layton main visual identity ? I think that a logo without a hat would have been enough. Thus, the hat symbol would have been exclusive for
Hershel identity. That's just my opinion.
