Prince Rudolfo

Born from the imaginations of Stan Lee and Jack Kirby in the very first issue of Astonishing Tales (1970), Prince Rudolfo is a Silver Age Marvel creation with genuinely prestigious origins — you don't get a more storied debut team than that. His appearances place him squarely in the orbit of Victor Von Doom himself, which tells you something about the regal, high-stakes world he inhabits. Though his catalog footprint is small, the company he keeps — including Ka-Zar and his sabretooth companion Zabu — spans some of Marvel's most adventurous corners of that era. A rare find for the dedicated Silver Age collector, Prince Rudolfo is a fascinating footnote with a legendary pedigree.
