According to someone who knows a lot more than me,
Comic book covers based upon famous images, from other comics or elsewhere, areI think the whole idea is great, but I also think that certain images end up being over-used, and the Steranko Hulk cover is one of them. Not wanting to be left out, I've decided to use it as the image for the next Mighty Mailbag page.
commonly referred to as “homage covers”. As the term implies, homage covers pay tribute to revered “touchstones” of comic book, pop cultural or even “real world” historical imagery. They also provide a sense of fun and community, as seasoned fans recognize the visual as the hat-tip, the nod, the gentle satire or the arcane “in-joke” knowledge it was intended to be.
