1966 OPC Batman Black Bat #40 Following the Clue

Centering estimate: left border ~10%, right border ~15%, top border ~12%, bottom border ~13% — approximate L/R ratio 60/40, T/B ratio 48/52, centering is decent but slightly right-heavy; no miscut visible. Corners show light to moderate rounding on all four, most visible at the lower-left and upper-right, consistent with EX to VG-EX range. Surface gloss appears partially intact with some dulling evident, typical of handled vintage stock; a small area of surface wear or possible light soil is visible near the lower-left border. No creases are clearly visible in this photo, though the card shows enough corner fatigue and gloss loss to suggest a grade floor around 4; without a back scan and corner close-ups, the upper bound is conservatively set at 6.
