These bookstacking mods look great right over the book insert on the game.  These multi colored stacks of books are hand made and assembled together  with a steel post through the center for added strength .  A custom shaped steel bracket is painted black and blends in well with factory brackets. Easy installation.  A nice simple mod that really enhances the empty area right in the middle of the playfield over the captive ball area. Highly detailed mod. Approx. 2" wide by 3.25" tall.
