Autograph Authentication – Eric Dickerson

Confidence Grade: B (Likely Authentic)

---

Overview

This autographed 1000 Yard Club football trading card bearing the image and name “Eric Dickerson” shows a large blue ink signature over the photograph. The signature displays natural variation, apparent velocity changes, and elements of handwritten pressure dynamics. No immediate signs of digital reproduction or mechanical signatures (e.g., autopen) were found. The ink-to-surface behavior is consistent with a marker penned over standard gloss card stock.

Candidate Identity (Investigative)

• Eric Dickerson – High Confidence: The signature exhibits similar flow, dominant “E” formation, and characteristic loop structure as seen in authenticated Eric Dickerson autograph exemplars, especially those signed with markers on gloss material.
• No other candidates reviewed, as stated name “Eric Dickerson” in tandem with a strong visual match supports identity confirmation.

Forensic Ink and Substrate Evaluation

• Ink Type: Likely permanent marker (e.g., Sharpie), with strong, saturated strokes characteristic of freehand marker use.
• Ink Flow & Pressure: Evidence of variable ink density and stroke weight, particularly near the beginning and terminal portions of certain characters, indicative of live hand dynamics.
• Surface/Substrate Bonding: Ink lies atop the card’s glossy surface with no evident feathering or ink bleeding, consistent with a live signature on high-gloss cardstock.
• Reflection/Sheen Test: Image shows differential reflection consistent with pressure-applied glossy marker ink—distinct from machine gloss overlay or photo-print patterns.

Individual Signature Analysis

• Stroke Characteristics:
• The capital “E” exhibits fluid entry/exit strokes, mid-stroke variation in angle, and pressure modulation consistent with quick hand movement.
• “Dickerson” transitions with rhythm and mid-range slanting, and the descending letters (notably ‘k’ and ‘r’) show deep loops and terminal flicks.
• No pixel-pattern repetition noted, ruling out autopen involvement.
• Micro-wobbles & Line Continuity: None detected. Long, curved strokes flow naturally without mechanical conformity.
• Start/End Tapering: Present. Entry points begin with lighter pressure, and exit strokes diminish in ink saturation, supporting live signature evidence.

Collective Signature Analysis

• The autograph lines up well with the contextual space provided by the card and does not disrupt underlying imagery in an unnatural pattern (e.g., no floating alignment).
• Multi-directional ink stroke behavior (some upward, some downward) supports a handheld signing motion.
• While slanting and hook shapes vary naturally, they retain consistent stylistic elements seen in known Eric Dickerson signed memorabilia, suggesting genuine authorship by the same individual across different items.

Red Flags

No major red flags found, but the following minor concern is noted:

• Plastic Enclosure Artifact Risk: The signature is behind a clear sleeve or plastic barrier. Refractive glare somewhat inhibits the certainty of full ink penetration analysis. However, the visible ink behavior is consistent with live application over gloss.
• Provenance: No contextual or provenance documentation is provided with the item. This slightly reduces confidence, though physical evidence outweighs that deficiency.
