One of the reasons I adore reading old comic books in their original "floppy" form is the advertisements. If you buy the trade paperback you miss all of these hilarious or fascinating ads they used to publish. The older the comic, the better. Read a comic book today and the ads are all for deodorant sprays, cars and TV shows. Read a comic for 1982, and you get ads like this: selling Dungeons & Dragons to the kids of America. This one's from the back cover of Marvel's ROM: Spaceknight #28, dated March 1982.
