Here's an early piece by the nigh-legendary John Byrne: the cover of the pos-Apocalyptic science fiction series Doomsday +1, published by Charlton Comics in the mid-Seventies. Written by prolific Charlton head writer, Joe Gill, Doomsday +1 was a surprisingly smart adventure series, and one of the best books ever published by the Derby, CT company.
Byrne's art on the title was remarkably accomplished, considering his inexperience at the time, and his work on this title, as well as the latter issues of the company's Space: 1999 comic, still ranks as some of my favorite comic art, ever. In fact, I prefer it to much of his later work for Marvel and other companies.
Another cool thing about this cover – aside from the trademark Byrne robot and the great composition – are the colors, which, when looked at closely, have clearly been rendered in magic marker! Great stuff.
