Comic artist Jock tweeted yesterday about the archive library he saw while touring DC Comics HQ, and shared a few pics:

According to Bleeding Cool, this vinyl single was meant to come with The League Of Extraordinary Gentlemen: The Black Dossier but was scrapped due to copyright issues. If your first thought was “I want to know what’s on that!,” you’ll be glad to hear it was later released in the UK in a limited run issued by Gosh Comics, and from there uploaded to Youtube:

Other fun finds include an original print of Help Keep Your School All-American, and a snippet of something extra rare and surprising:

I was so distracted by the wonderful line work, it took me a moment to realize what I was looking at. A life in the family! I hope I get a chance to view the rest myself some day!
