takin it back! this was cover to Wildcats v3.o done about 5 years ago.
it was intentionally done using a layout similar to one of Jim Lee's original wildcats covers ( i forget what issue). we just replaced them with our new characters.
the original was done with a flat construction pencil from homedepot and sharpened with a toothed kitchen knife to get the multiple lines. i remember showing Jim the piece online and he asked " so are you tired of drawing with a regular pencil?"
