Much like he did for his 5 Ronin covers, artist David Aja has posted his preliminary sketches for his Red Skull Incarnate covers, for which he pulled inspiration from Nazi war propaganda posters.

"I did extensive research into historical documents for the styles," he said on his blog. "In order to make that work, I used different typographies each issue, emulating different typefaces in real work; so I needed a uniform tone, technique and color in the finished art to identify all the covers as a whole collection."

The five-issue miniseries by writer Greg Pak and artist Mirko Colak kicks off in July.
