A side by side comparison shows that a number of panels on the original art pages have the relettered and pasted over dialogue but some do reveal the original. Published in beautiful color in EERIE # 60, this is one of my favorite Wood pieces (done with Paul Kirchner?). The mag does not list a writer (or an artist for that matter) but a later reprint credits Warren regular Gerry Boudreau. I've also heard it said it was Bill DuBay, who rewrote so many of Wood's later works for Warren.
The story, in this case, appears to be essentially the same so I'm not sure why someone felt the need to rewrite the piece so substantially.
