This Dan Adkins TALES TO ASTONISH illustration really isn’t anything special, but what makes this cover noteworthy is the monochromatic blue color, in this instance applied even to the corner box and Marvel logo. Stan Lee would occasionally favor such an approach to a cover, often to good effect (as on the X-MEN #17 cover we ran previously) and sometimes to poor effect. But this is the only blue monochromatic cover that I can think of, and it leaps out from amidst any stack of comics as a result.
