3. Iron Maiden: Killers

Yes, another Iron Maiden cover in the list, but I've included these purely for the unbelievable calibre of the artwork, and not because of the fact that they are my absolute favorite band on this planet. I feel that this cover shows Eddie in his most menacing avatar. Even though the art doesn't feature any other character, little details can be extracted by taking a closer look, such as the location being a real-life one, shown by a partially visible sign in the background that reads 'Ruskin Arms', a legendary club where Maiden used to perform during their earliest days as a band.
