Just look at this DC cover by Russ Heath.We have an eye-catching battle scene shown from an unusual perspective and like most of DC’s war covers it looks great. Back in the days of spinner racks, a good cover was a tool screaming that readers should put their money on this comic, not the one in the next slot. They had to be good (though they weren’t always, of course). Today, with dedicated comics fans shopping in specialty stores, there just isn’t the same need for an eye-grabbing cover.
For more examples that I’ve posted before, here’s one by Carmine Infantino—And a favorite by Murphy Anderson.#SFWApro. All rights to images remain with current holders.
