There were two sheets in the bonus. Each was in glorious full color, with a 5x5 grid of 25 squares. Each square was a 1 1/2-inch-by-1 1/2-inch reproduction (most not actual size) of a portion of an album cover. Teams needed to ID the album title and its artist. Were this not a sober, unbiased historical archive, where unsubstantiated opinion would only undermine the serious nature of this enterprise, we would point out that this was THE GREATEST TRIVIA BONUS EVER.
