We've seen a lot of things come back into style over the year from the 60's, 70's, and 80's, but sadly the mural custom painted on the sides of a custom deliver van (with waterbed in the back) hasn't made a come back yet.
When I was in high school I saw this picture of a guys tricked out van, painted in a Pink Floyd theme, with bed and disco ball in the back and I wanted one so badly.
Luckly good taste sometimes comes with age. But with all the other tacky retro things that have come back, I'm surprised the tricked out van never has.
