I too like that website. I have played around with taking the images of the ads, and recreating them as high quality pdfs. Maybe I'll post some that I tried.
 
Great, MisterKeeks! I am actually currently trying to find a Macintosh Plus add that I can use as a source for a wallpaper for my room, but didn't find something that served my ideas. (If I can't possess it, at least I want to have the wallpaper ;)
