Hahaha, I thought exactly the same thing. "Why is she trying to HIDE her face? Why is she trying to CONCEAL her features from everyone?"
I do love in these old comics what a complete jackass Superman is all the time. Like him mentioning that no woman could possibly go out without her makeup kit unless she was too ugly for makeup to be of use. And also doing things like reading Lois' diary, hurling drill-saws at her, ordering her the milk, etc. It's really a wonder that she wanted to marry him after some of the crap he pulled.
