The text in the catalog is actually the capper: the consummate "girl next door," Mary Jane discovers that her superhero husband has slipped some of his laundry into the mix, but she's not looking too displeased about Peter's naughty little transgression. ...um, yeah.
(Also: MJ? Not the girl next door. I know in the movies she is, but in the comics, she's not, and one of the things that makes her so interesting to Peter in their early days is that she moves in completely different circles than he does.)
Who the heck buys these things? It ain't me.
