Nice reverses. I assume it is not American Bank Note because I don't see their name on it. Don't cry for me.
Are we to assume that blank oval was for the guy's wife? And either he's not married, divorced, or he killed her in the revolution riots.
You'll often get blank ovals when there's a watermark to be shown, as this sets aside a space to easily see the mark. Otherwise, you'd have to squeeze it somewhere else and it's a bit crowded to do so.
