JSA#46, pages 2&3: This was simply a case of the office accidentally giving Sal the incorrect reference for Mordru. Sal rendered him in the outfit as seen in the top image and for the next 4 pages (which I was inking) before we were told that he was supposed to be wearing Dr. Fate’s uniform.
Sal redrew on new boards all of the parts that would need corrections and mailed them to me to ink and then cut & paste onto the original art. This image shown was an example where the original art had been sent to DC Comics already so they received the fixed images by us and made photostats of them to paste down onto the art.
