I have gaydar for book covers.
[above] Book cover type may have implications you’ve never thought about. Here are two book covers showing men in frilly shirts. If not for the typefaces, could you tell that one book is intended for straight women and the other for gay men?
Either illustration could appeal to people of either gender and orientation but the type makes the difference. The Cross Bones type could be used on a book for straight men, but not with a guy in a frilly shirt.
