When Freddy Freeman is attacked, his back broken and his grandfather killed, by Captain Nazi, Captain Marvel seeks permission from Shazam to help the poor boy. He is allowed to give Freddy some of his powers....so, when he says the name of his benefactor, Freddy becomes Captain Marvel, Jr.! Though weak and poor as Freddy Freeman, Captain Marvel Jr. fights powerfully against Nazis and criminals both – through a long run in Master Comics and his own magazine, plus appearances in Marvel Family and other titles. Gwandanaland / Midcentury Comics has the largest collection of the WORLD'S MIGHTIEST BOY in print! THIS IS AN UGLY BOOK – We published this book by request and (pathetic) begging, but it is not a pretty sight. It contains close to 20% of the pages from low-resolution and poor-quality microfiche, and many of the other pages are damaged and/or aged. As new files and issues are located and scanned we will update this book, and when it has reached the right level of quality we will offer a free replacement, but if you get this book, in the meantime we hope you will enjoy its very imperfect authenticity.
