You’re not supposed to judge a book by its cover, but it’s okay to judge a cover on its own.

The minimal elements convey a vivid message, whether it’s a lone ship crossing a seemingly endless ocean or the legs of a man merging with with the head of a ravenous beast. If you miss the declining prevalence of cover art in our digital age of downloads and blank CDs from Best Buy, take a look to celebrate a different era.
