Subliminal sexy talk

There's this issue of Superman's Girlfriend Lois Lane. It features Supergirl secretly trying to convince Superman to to fall in love with Lois by making him see her every where. She quickly swoops in, alters a billboard, then back out again. Superman thinks, "I'm seeing her every where, I must be in love!"

It's cute little story. It's actually kind of sweet, Supergirl wants Supes to marry Lois so they can adopt her. Awwww. One of the billboard switches, as seen in the original printed comic, looks like this-

The full billboard's never shown, so I have no idea what we're meant to be trying. According to the original art however, Supergirl wants Superman to try something dirty!

Yeah, that's a crappy picture, but the intent is clear. That thing says Try Lust. Supergirl was a closet freak.

My dad actually recognized the product it was meant to be an ad for. There used to be a shampoo called "Lustre Cream" and its ads encouraged you to "try Lustre Cream."
