Autograph Authentication – Oscar Piastri
Confidence Grade: B (Likely Authentic)
Overview
This report evaluates the authenticity of an autograph attributed to Formula 1 driver Oscar Piastri, observed on a holographic Topps F1 trading card. The signature appears in black ink directly over the card’s gloss finish. Initial visual impression suggests a fluid, freehand signature with pressure variation and natural line morphology.
Candidate Identity (Verified)
- This analysis proceeds under a verified identity claim: Oscar Piastri.
- The visual structure of the autograph matches trustworthy exemplars from authenticated Formula 1 memorabilia and trading cards attributed to Piastri (2022–2023).
- There is no evidence of contested identity, so full analysis continues under the assumption of the stated signer.
Forensic Ink and Substrate Evaluation
-
Ink Type & Behavior
-
The ink exhibits mild gloss, indicative of a permanent marker or felt-tip pen.
-
There is conformance with the holographic surface, which shows minor ink pooling and slight optical ink diffraction—consistent with real ink over reflective laminate, not pre-printed graphics.
-
Evidence of stroke tapering is visible in both entry and exit zones of the curves, particularly in the beginning and mid-curve areas.
-
Substrate Interaction
-
The ink appears to sit atop the laminated surface, consistent with authentic in-person signatures on cards.
-
There is no evidence of ink bleeding or fiber diffusion, which further supports it being on a synthetic-coated trading card, not porous paper.
-
Vertical lighting and glare confirm the light scattering consistent with wet-ink application as opposed to printed material.
Individual Signature Analysis
-
Stroke Flow and Pressure
-
The autograph exhibits natural stroke fluidity, particularly in the loop and tail structures.
-
Variable pressure is visible in both the vertical lift and rounded strokes, suggesting hand-applied force rather than uniform mechanical line weight.
-
Pen Lifts and Line Dynamics
-
There is one visible pen lift in the transition between letter segments, not easily reproducible in autopen or printing systems.
-
Thick-to-thin line variation appears consistent with alternating pressure and writing speed.
-
Baseline and Rhythm
-
While slightly stylized, the signature maintains a steady rhythm and midline consistency, aligning with known Piastri exemplars.
-
No extraneous “wobble” or pixel matching consistent with autopen mechanisms was detected.
Collective Signature Analysis
- There is only one signature on the card.
- Taken as a whole, the image reveals:
- A human signature done over the card’s surface after printing.
- No duplication, smudging, or disturbed detail that may suggest replication or transfer.
- Ink alignment respects the curvature of the gloss surface, visible in reflected light feedback.
Red Flags
- None Detected:
- No signs of autopen, pre-print, ink transfer, laser or inkjet reproduction.
- No pixel-perfect replication.
- No unusual pen behavior or surface inconsistencies.

Conclusion: The detailed forensic analysis of ink behavior, stroke characteristics, and surface interplay shows strong evidence of an authentic, hand-signed autograph. The piece lacks indicators of autopen, print, machine duplication, or forgery. Cross-reference with marketplace and exemplar materials supports authenticity.
Final Confidence Grade: B – Likely Authentic.
