I'm a sucker for gray scale illustrations. I like the hat although the hat band is a bit too pronounced. And, of course, I don't care for the scarf but other than that I like this little sketch.
So simple yet so very effective. I try to look at these through the eyes of a young me if I were seeing them on the stands for the first time. The two weeks (and later whole month) of anticipation between issues would have me at the newsstand the day it was supposed to hit the racks. I do the same thing at my local comic shop these days with the reprints. This cover would've have gotten me very excited to know what lay beneath the cover.
After the Thanksgiving holiday this week Under the Blue Light will try a new game. Not sure if it will be as easy as the cover clews that have been shown the past few years, but here's hoping the Master's agents will give it a whirl, nonetheless.
