There was an excellent show at the Vancouver Art Gallery last year which highlighted Krazy Kat very well, called KRAZY! The Delirious World of Anime + Comics + Video Games + Art. It's touring in truncated form in New York now, but they apparently dropped the comics angle (though "KRAZY" is still the title). If you get a chance to see the full show in the future, take it.
Anyway, it's been a few days since I posted any comics stuff: was busy with other writing, including this little model-making spin-off from my Star Trek researches of last week. Next up in the comics section should be a piece on the great Charles Addams.
