Arthur Phillip
This portrait of His Excellency, Governor Arthur Phillip, first governor of New South Wales was painted in 1786, just outside the Regency period, but it was too good not to let you know about it. Maybe an honourable mention? Your discerning readers will no doubt appreciate it.
I’m not sure what’s going on there. It looks less like elephantine genitals than a built-in cushion.
[Editor’s note: Holy moly that is some serious camel toe]
