Hey guys,
I want to make a poster for my room (roughly the size of a posterboard,
but perhaps larger) and the premise is that I would take a single panel
(or a few) from an old-fashioned comic and enlarge it to poster
size.  When I was touring colleges 3 years ago I saw it done, and
I was impressed.  The guy who did it used the simple grid method
to blow up the image, and then painted everything, and it was done very
well.  What he did has always stuck with me and now I finally want
to do the same thing.
So -- my problem is actually finding a resource image to expand. 
I've google image searched for quite a bit, but not knowing exactly
what to search for, the closest thing I could find to what I want is
this image:
 
But that's way too small (and merely just a hint at what type of image I'm searching for).
I want that old style, and I don't want something that's too iconic
(ie. No Action comics or recognizeable superheroes, just random Dick
and Jane type comics).
I don't really know my comic history, so I can't even put it into
words, but I'm basically looking for something that uses the halftone
dot style that looks sort of like this:
 
I apologize if I'm being longwinded or vague, but you guys are a
tremendous resource and I would appreciate any suggestions or links you
could provide.
Thanks in advance!
