Best news I've heard since they started collecting the Max Raboy FLASH GORDON dailies together (now THAT was one handsome release; that pure white, stiff paper, the dustjacketed cover, all done, thankfully, without shrinking or reduction).
I haven't heard of this! Who released them? And do you happen to know if there are any Mac Raboy Captain Marvel Junior collections? I've tried Googling this, but all I've found out is that Mac Raboy is a gay icon.
