Great Page by Steven Grant, Mike Zeck and John Beatty

Recently iFanboy picked the art above for their Great Pages feature.  The page is identified as …

from The Punisher (Vol. 1) #1 (1986)… written by Steven Grant with art by Mike Zeck.

While that is correct, I wonder why inker, John Beatty was not mentioned?

C’mon, iFanboy!
