Released in 1966, “The Marvel Super Heroes” is the great-grandfather of modern Marvel Studios entertainment.

Not only the very first series based on Marvel characters, the cartoons were created using xerography — meaning that images were copied from the comic books themselves and manipulated to appear fully animated. Only the show’s music, composed by Jacques “Jack” Urbont, was wholly original. True “when you know it, you know it” oddities among the company’s decades of projects, adaptations and spinoffs, its themes were seared into the brains of generations of fans before being largely lost to history.

In honor of Marvel’s 85th anniversary, Disney Music Group is officially releasing Urbont’s music for “The Marvel Super Heroes” — much of it for the first time. And it’s all coming on vinyl: Following the July 12th launch of a 7” set featuring “Merry Marvel Marching Society,” DMG and Hollywood Records will release “Captain America” on August 9, with “Iron Man” due out September 6. Featuring remastered audio and packaging artwork faithful to the Jack Kirby, Steve Ditko and Don Heck comics that inspired the show, the records offer fans a nostalgic collectible that harks back to one of the first times the company’s heroes leapt off the printed page.

Aside from a few limited VHS releases of the show, some sporadic Easter-egg bonus material, and a handful of European DVD releases, the best way to hear the music is via songs and albums by hip-hop artists who have sampled it, like Ghostface Killah and MF Doom. Given the complex legal history of Marvel merchandising — let alone the age of the material — Paulo DaCosta, Disney Music Group's president of marketing and product management, says sorting out the rights was a years-long process. "It took a minute to figure everything out," DaCosta told Variety . "These things take time, the restoration, the remastering, all the art approvals, we had to make sure we were on top of everything."
