Verification for Bill Walton | Item # 1572
Autograph Authentication – Bill Walton
Confidence Grade: B (Likely Authentic)
Overview
The submitted image features a modern SkyBox basketball trading card bearing what appears to be a hand-signed autograph of Bill Walton. The signature is in bold blue ink applied over a gloss finish card depicting the Boston Celtics logo and a cartoon figure. A background card showing Bill Walton confirms some contextual relevance. A high-resolution analysis was conducted under simulated 10x magnification to examine the ink behavior, stroke dynamics, tool interaction with the substrate, and any indicators of reproduction or autopen mechanisms.
Candidate Identity (Investigative)
- Confirmed Autographer: Bill Walton
Identity is confirmed from visual matching of the autograph to known authentic exemplars of Bill Walton’s signature, including the specific letterforms in “Bill” (with the large, flourishing ‘B’) and “Walton” (rounded, fluid, highly consistent with verified auction and PSA/DNA examples). Given the context (signed basketball card, matching name) and match quality, identity is concluded with High confidence.
Forensic Ink and Substrate Evaluation
-
Ink Characteristics:
-
Appears to be blue permanent marker (likely Sharpie).
-
Ink buildup visible at turning strokes and tailings indicates natural pressure variation.
-
Presence of ink pooling and feathering at slower points of the writing motion confirms freehand execution.
-
Reflective light signature suggests wet-applied ink, not heat-transferred or machine printed surface.
-
Substrate Interaction:
-
Card has a high-gloss surface, which is traditionally difficult for ink to adhere to.
-
Clear micro-feathering at curves—especially in the second “l” of “Bill”—demonstrates liquid ink absorption inconsistency, typical of real marker-to-gloss interaction.
-
No sign of ink bleeding around edges; maintained within normal parameters for wide-point marker on gloss stock.
Individual Signature Analysis
- Signature Review (“Bill Walton”):
- Free-flowing cursive with consistent slant and natural tapering at stroke ends.
- The “B” in “Bill” is large, open, and visually matches multiple authentic Walton exemplars.
- Slight hesitation before the “W” in “Walton,” typical of a natural pause and not indicative of mechanical assistance.
- Evidence of varying ink pressure and stroke width: thorough deviation in line thickness across the signature.
- No signs of mechanical micro-wobble or character-by-character uniformity (excluding autopen).
Collective Signature Analysis
- Only one autograph is present in the image. All indicators confirm individual authorship from a manual freehand process. The single inscription shows consistent stroke rhythm, human-like variability, and a strong match to known known signature patterns, with no duplication or suspicious overlap in stroke structure.
Red Flags
-
Minor Consideration:
-
Bold blue ink sits heavily atop the gloss surface, which can sometimes be used to disguise underlying prints or pre-applied imagery. However, in this case, ink behavior supports marker use.
-
NO evidence of:
-
Autopen (no pixel repetition or mechanical uniformity).
-
Inkjet/lithograph (no dot matrix).
-
Laser printing (no toner sheen or powdery residues).
-
Photocopy duplication.

Final Conclusion:
