Muhammad Ali (born Cassius Clay)

Era

Dated August 2, 1981 - Post-retirement transition period

Item Type

Signed card/slip matted with a 16x20 or 20x24 photograph

Condition

Excellent; the signature remains bold with minimal fading; paper shows slight natural toning consistent with its 1981 age.

Rarity

Moderate; while Ali was a prolific signer, early 1980s examples in good condition on non-standard mediums are highly sought after.

Overall Assessment

This is a high-quality, authentic specimen from a desirable era, perfectly paired with his most famous image. It is an ideal piece for serious collectors.

Authenticity Assessment

Highly likely authentic with high confidence level based on fluid cursive and character-specific traits.

Signature Style

Full cursive signature with the 'from' inscription above and 'Aug 2-81' date below; featuring the classic loop-and-overlap flourish.

Signature Characteristics

Strong vertical slant, consistent pressure, well-formed 'h' and 'm' loops, and the distinctive isolated 'A' with the drop-down 'li'.

Ink & Medium

Blue ballpoint pen on an off-white paper slip or index card; shows natural ink distribution typical of early 80s pens.

Item Description

The autograph is on a small paper medium, professionally matted beneath the iconic Neil Leifer photograph of Ali standing over Sonny Liston.

Estimated Value

$600 - $900 USD (matted with iconic photo; value increases with PSA/DNA or JSA certification).

Comparison to Known Examples

Displays identical letter formations to verified 1980-1982 exemplars before his hand-shaking became more pronounced in the mid-80s.

Authentication Tips

Look for the characteristic 'continuous-line' flow between the 'M' and 'u' and the specific height ratio of the 'A' in Ali.

Certification Recommendation

PSA/DNA or JSA (James Spence Authentication) are the industry standards for Ali memorabilia.

Red Flags

No significant red flags observed; flow is too natural and swift for typical slow-draw forgeries.

Provenance Notes

The specific date (Aug 2-81) provides a strong anchor for tracing local events or signings occurring on that day.

Historical Context

Signed less than a year after his penultimate fight against Larry Holmes, during a time he was still very active in public life.

Market Trends

Stable and appreciating; Ali remains the blue-chip standard for boxing memorabilia worldwide.

Investment Potential

Excellent long-term hold; authenticated Ali signatures on iconic imagery are staple assets in sports collecting.

Similar Autographs

Joe Frazier, George Foreman, and Mike Tyson; though Ali carries the highest premium.

Display & Preservation

Requires UV-protective glass and acid-free matting to prevent the ballpoint ink from fading and the paper from further yellowing.

Interesting Facts

Ali was known for being incredibly generous with fans, often signing for hours, which led to a diverse range of signature styles over his life.
