Alpha Flight makes appearances in two upcoming books about to be released.
Sasquatch and the Alpha Flight Omnijet make it into Insight Editions Marvel Vehicles: Owner's Workshop Manual. They are the same people who made the World according to Wolverine that Phil mentioned earlier.
It's like an Official Marvel Handbook for vehicles. I saw a preview copy at NYCC today.
Also, Alpha Flight appears in the biggest BIGGEST book in the Alpha Flight collection: 75 Years of Marvel Comics. From the Golden Age to the Silver Screen by Taschen. It's a monstrous oversized 712 page book that weighs a ton. You can see Puck reprinted on the cover of West Coast Avengers #1 and there's a blurb about Northstar and Kyle's wedding with a reprinted cover of Astonishing X-Men #51.
Did I say how big it is? It's so big.
