Are comic books really 'comic' or even 'books' The question is debatable, but there is no denying that comics are big business. There are entire small stores devoted to just comic books.
Despite the term, the subject matter of most comic books is not humorous. The term 'comic book' came about because the earliest publications were reprints of newspaper comic strips, which were funny in nature. Sometimes comic book is called comic magazine.
But you can depend on Disney comics to be amusing. Just the characters themselves evoke a smile. Highly collectible vintage comics will be about Mickey Mouse and Minnie Mouse and …their friends, of course. Check out eBay for current offerings.
