Backing up slightly to male surnames and female first names, a recent election here made that trope painful and obvious.
In serious, stately fonts, the surnames of male candidates.
Smith
Johnson
Jones
In breezy, casual fonts, some resembling handwriting, the first names of female candidates. some with exclamation points at the end, stars or hearts dotting the letter i, and other fun stylings.
Maggie!
Louise
Lovely (her given name)
This really bothered me, that the women had to make their signs likeable while the men had to be serious. Of course, any woman who's too serious is called a bitch, so there's that.
