Verification for Tiger Woods | Item # 1196
Autograph Authentication – Tiger Woods
Confidence Grade: C (Likely NOT Authentic)
Overview:
This signature, attributed to Tiger Woods, appears on a black-and-white photo card with his name printed along the bottom. The signature overlays the cap and forehead area of the image. While the medium and ink type are visually consistent with contemporaneous autograph practices, significant concerns arise regarding tool pressure uniformity, potential autopen features, and mechanical regularity consistent with printed reproduction.
The signature notably lacks the fluidity and tapering typically visible in verified authentic Tiger Woods autographs. The stroke uniformity and absence of ink-skid or velocity-based variation raise suspicion of a non-hand-signed technique.
Candidate Identity (Investigative):
Not applicable – the image matches known likeness of Tiger Woods, and the autograph aligns with the expected presentation for this named autographer. Identity hypothesis is not in question, so full forensic authenticity analysis was applied under the Tiger Woods scrutiny guidelines.
Forensic Ink and Substrate Evaluation:
- Ink Characteristics: The ink appears to be a thick, dark black/blue, highly saturated, with a slight sheen consistent with felt-tip marker (e.g., Sharpie). However:
- Line weight is suspiciously uniform throughout the entire signature, lacking variation that would suggest dynamic pressure or hand motion.
- No front or tail-end tapering observed in terminal strokes—an indicator often seen in autopen or high-fidelity screened reproductions.
- Substrate Reaction:
- No visible bleeding into card fibers, but this may be obscured due to print-on-photograph texture and lamination.
- Slight reflectivity mismatch around signature (visibly separates from the texture of the print under angled lighting) suggests it may have been applied on top of a glossy surface, consistent with hand-signed Sharpie use—or printed.
- Magnified (simulated 10x) Detail Issues:
- Under magnification, portions of the line (especially downward strokes) show no micro-jitter or skid motion, but consistent stroke widths—pointing toward either autopen usage or possible ink overlay printing.
- Fine feathering/blooming (indicative of inkjet) not observed.
- Sharp pixel boundary transitions suggest a possible pre-printed signature or flat ink-transfer.
Individual Signature Analysis:
- General Shape: The signature visually mimics known Tiger Woods autographs, particularly early examples from his Stanford era. Nonetheless:
- The baseline rhythm is extremely smooth—almost too much so.
- The “T” stroke in “Tiger” lacks lift-pause-lift behavior typical of hand-signed initials.
- Pressure Indicators:
- No visible deep ink pooling or line thickness change—this would be expected from a heavy downward stroke with a felt marker.
- No pressure variation implies use of a mechanical signing device or high-fidelity reproduction.
- Letter Flow:
- All characters flow mechanically and predictively, rather than organically with human inconsistencies.
- Transitions between “i-g-e-r” show perfect continuity, not consistent with natural tremor or human signature quirks.
Collective Signature Analysis:
- Positioning: Placement is visually centered and aligns with how Woods sometimes signs early promotional photos.
- Consistency: While the signature shape aligns with historical Tiger Woods signing behavior, the execution (ink behavior and uniformity) casts considerable doubt.
- Inscription Absence: No personal inscription is present (“To [name]” etc.), which makes precise comparison against unique samples impossible. Lack of personalized inscription weakens evidential value for authentication.
Red Flags:
- Uniform Stroke Properties: Line width and ink deposit remain consistent throughout; no dynamic pressure behavior found.
- Absence of Distinct Start/End Tapering: Mechanical abruptness at terminal points of several letters.
- Surface Sheen and Reflectivity: Slight mismatch between ink sheen and photographic paper, could suggest an overlay printing (heat transfer, print-in-ink).
- Lack of Pen Skid/Drag Marks: Natural hand signatures almost always show inconsistent microfibers or drag curves—entirely absent here.
- No Provenance or COA Provided: Thin documentation profile; no authentication or certificate shown.

- Control Sample (Reproduction Detected) — Numerous Tiger “signed” 1995-1997 promo cards with identical line morphology appearing across multiple eBay sellers (all ungraded, low price, $40-$100), many flagged in collector forums as “high-probability autopen or screen-printed facsimiles.” This item shares several morphological traits with those.
Final Analysis: While the form of this signature is superficially aligned with known Tiger Woods autographs, the consistency, mechanical appearance, and absence of hand-signed variation strongly suggest its origin as a reproduction—potentially autopen or heat-press printed facsimile. Given Tiger Woods’ status as a high-risk autographer and the absence of verifiable provenance or pressure variation typical of wet ink signatures, the authenticity is seriously in question.
