The Don Rosa Duck Library Vols. 5 & 6 (Box Set)
Scrooge McDuck risks destroying the planet when he thinks a serum that can bore through any surface might instantly dig mineshafts but instead he drills a tunnel straight into the Earth's core. Also included are "Hearts Of The Yukon" and "The Lost Charts of Columbus" plus more! Presented in brilliant color with a treasure trove of Rosa's cover art and behind-the-scenes factoids. Also available is a new boxed set of this volume and last season's Vol. 5!
