1966 A&BC Batman Riddler Back #31

Centering estimate: left border appears wider than right (approx 70/30 left-right), top and bottom borders appear roughly 55/45 — centering is noticeably off horizontally. Most critically, there is clearly visible handwriting/ink markings across the front surface of the card (green/blue script letters visible across the upper portion of the image area), which is a major surface defect that PSA would typically qualify with an 'MK' (marks) designation and cap the grade severely, often at PSA 2 or lower. Corners appear rounded and show wear consistent with a card that has been handled. Gloss appears significantly diminished. The combination of writing on the card face, corner wear, and border issues makes this a low-grade candidate; the writing alone is typically grade-capping at PSA 1-2, and the card may receive an MK qualifier rather than a clean numeric grade.
