Publisher’s description
Superboy and Captain Marvel ride the rickety roller coaster (literally) through the many-hued amusement park of motley meteoroids that is the Kryptonite Spectrum. With Superman now a bit... shorter in the tooth... the Boy of Yesterday must team up with a truly Marvelous friend in a story for the ages... for all ages. What, exactly, is Nostalgia Springs? And what do Toyman and Sivana have to do with it? Find out in this great adventure — chock-full of crayons, Kryptonites , and a cruise through comics chronology!
