Classics Illustrated was a comic book series originally published between 1941 to 1971. The comics in the series were abridged adaptations of famous literary works. A total of 169 titles were published during this period.
I feel that there is an innate charm to these books that can never be replicated by modern day comic book artists. So I was quite pleased (to put it mildly) to find this site which features scanned comics from the series.
These are some of my favorites: The War of the Worlds, Rip Van Winkle, Frankenstein, The Iliad.
