Theres a Blog I follow called..."The Brave and the Bold the lost issues." I enjoy the work that ROSS the author of the blog puts into each and every faux/mock imaginary team up cover he posts. It reminded me of a time when comics were much simpler and the trade of graphic art was more....dare I say? Artistic.
Simple pencil drawings with black and white line art and the 4 color process all wrapped up in one story.
