Compiled by BBC writer Adrian Besley with contributions from the surviving Pythons, the $40 book, in stores now, compiles never-before-seen photos, artwork, script pages, and notes, as well as reproductions of memorabilia and links to online clips spanning the comedy troupe’s entire history, from their collegiate improv roots up to their recent reconciliation and reunion tour.
