Classic...but not too classic...Charles Addams!
My wife didn't know the Addams Family was a comic waaaay back when, so I found a couple books at my local library and checked them out.
People really need to understand that Addams was way ahead of his time and guys like Burton, Gorey, Hitchcock, Dali, and the early Disney imagineers were influenced by him. I read reprints when I was a kid and it was some funny, dark stuff.
A lot of these are very dated and don't make the best of sense unless you're from that period in time. Personally, I prefer his earlier work from the 40's, 50's, etc....and many of these are from the 70's and have a bit of a beatnik feel to it. It's not the greatest of collections, but it's still Addams!
