Michael Chabon, the author of many books, among them The Amazing Adventure of Kavalier and Clay, has a website whose front page currently shows a poster for the Sitka World’s Fair. At first I thought this was a just an interesting retro poster from 1977. However, between the Yiddish on the poster and the fact that Sitka is not a bustling metropolis but rather an Alaskan city of under 10,000 people, I realized that this is an artifact from the alternate-history of Chabon’s upcoming new book The Yiddish Policeman’s Union. This book, due out in May, supposes that a Jewish homeland was created in the mid-twentieth century in Alaska, instead of in Israel, and extrapolates outwards from this premise (there was a proposal like this actually made during WWII, but it was voted down). I’m looking forward to seeing how he crafts this scenario.
