It is hard to describe the joy reading these brings me. This collection (we are told) is full Eisner after he returns from the war (some archives have fill in artists and writers) but I suspect he had help from his stable of artists.
There is such joy in the inventiveness of the art. Even today the fluidity and beauty and his ability to tell a complex story in 8 pages cannot be matched. Nobody draws rain like Eisner :).
There is such joy in the creativity of the stories. Every story is so unique. And even though it is framed with The Spirit there are different viewpoints, narratives, and often the Spirit is a secondary of very minor character. Eisner just loved telling stories.
I can't say any jumped out as "classics" but I loved them all. This was the beginnings of cartoons as a story telling medium and Eisner was a master and advanced the medium in a way nobody else has done since him.
I think my fav stories are the ones where The Spirit is blind and we get introduced to a new character - the rookie policeman Sam Klink. The Spirit always shines better when he has more supporting cast to bounce off of because - oddly - there isn't that much character development in him over the years.
Overall - I loved it. I wish I had all the Archives to read but they are very expensive and hard to find now.
