Muhammad Ali
Three-time World Heavyweight Boxing Champion and Global Icon · Boxing - Professional
Olympic Gold Medalist (1960), WBA/WBC Champion

Era
Mid to Late Career (circa 1980s-1990s)
Item Type
Signed 8x10 or 11x14 Photograph
Condition
Good to Very Good. The signature shows slight feathering; the photo exhibits minor silvering in dark areas.
Rarity
Common for the era, but high global demand keeps supply tight for high-quality authenticated pieces.
Overall Assessment
A highly desirable and iconic piece of sports history. The inclusion of a visible Steiner hologram adds significant confidence and value.
Authenticity Assessment
Likely authentic (pre-tremor to early Parkinson's transition period). Confidence: 85%
Signature Style
Full name 'Muhammad Ali' in two distinct segments, featuring his characteristic 'loops' on the M and A.
Signature Characteristics
Features a strong, slightly slanted baseline, smooth looped 'M' and 'A', and a characteristic dot over the 'i' that often blends into the final stroke.
Ink & Medium
Blue felt-tip marker (likely Sharpie) on a semi-glossy photographic paper.
Item Description
Black and white iconic image of Muhammad Ali standing over Sonny Liston (1965) after the famous first-round knockout.
Estimated Value
$600.00 - $1,200.00 USD (dependent on third-party authentication)
Comparison to Known Examples
Consistent with late 80s/early 90s sit-down signing examples where the signature remains legible before the onset of heavy tremors.
Authentication Tips
Look for a continuous flow in the 'Mu' and the specific height ratio of the 'l' and 'i' in Ali. Look out for mid-90s 'secretarial' signs.
Certification Recommendation
JSA (James Spence Authentication) or PSA/DNA are the industry leaders for boxing memorabilia.
Red Flags
Slight 'shakiness' could be misinterpreted as a forgery attempt, but here it appears consistent with early-stage Parkinson's natural variation.
Provenance Notes
The Steiner Sports sticker in the corner (SA73634) provides significant provenance once verified in their database.
Historical Context
The image captures the absolute peak of Ali's physical dominance and remains the most requested photo for him to sign during his lifetime.
Market Trends
Ali's market is blue-chip; values for his signature on the 'Liston Knockout' photo have increased steadily since his 2016 passing.
Investment Potential
High. As the most recognizable athlete of the 20th century, his high-grade signatures on iconic items stay ahead of inflation.

Display & Preservation
Recommend UV-protected Museum Glass and acid-free mounting to prevent the blue ink from fading into a brownish-yellow.
Interesting Facts
