According to Al Rubenstein, Jim Aparo believed that the face of the Batman figure had been pasted over his work. Rubenstein suggested the correction was done by Ernie Chan (pencils) and Romeo Tanghal (inks). Nick Caputo also believes Batman's face has been altered, but he suggests Joe Kubert as the corrector. Bob Bailey and Joe Rubinstein believe the cover is 100% Aparo.
