Demon in a Bottle is probably Iron Man's most famous storyline so it's only natural Marvel would want to pay tribute to it with their next line of variant covers. Last time it was Zombies, this time we get vampires. I would normally be skeptical of the idea, but using the non-reflection of vampires as the gimmick for the cover is brilliant. Kudos to Salvadore Larroca for his genius tribute cover to Invincible Iron Man #31.
