Pop Chart has a "100 Essential Novels" scratch-off poster. There are two versions of this poster with some slight differences. I have tried to make this reading challenge inclusive for both versions by making books that only appear on one version of the poster bonus prompts. 

For those curious about the bonus prompts, the original version of the poster has the following books: "I, Claudius"; "Dog Soldiers"; "Falconer"; "The Sportswriter"; and "2666."

Version 2 of the poster (which is the version currently sold on Pop Chart's website) replaces the 5 above with "A Visit from the Goon Squad"; "The Round House"; "The Underground Railroad"; "Lincoln in the Bardo"; and "Girl, Woman, Other".
