Remember those faked Marvel pulp covers by Calamity Jon Morris? Well, I've just came across these by Tony Fleecs (you may well remember his "adorable tragedies" series of illustrations), riffing on a similar theme. Fleecs will be selling prints of these designs at his many upcoming convention appearances (listed at his blog). More pulpy goodness can be found below.
See more of Fleecs work on his DeviantArt gallery page.
