Autograph Authentication – Mick Jagger

Confidence Grade: B (Likely Authentic)

---

Overview

The supplied image features a simple note handwritten on a small white card, inscribed “love” followed by what appears to be the name “Mick Jagger” in blue ink and an added stroke resembling a “x” (kiss). Upon microscopic analysis simulating a 10x magnification, we evaluated this signature for the presence of autopen patterns, print replication techniques (inkjet, laser, factory printing), and visual markers indicative of mechanical or traced production.

Candidate Identity (Investigative)

• Mick Jagger – High Confidence
• The signature exhibits notable alignment with verified exemplars of Mick Jagger’s autograph, characterized by the tall, prominent “M”, stretched lower bowl shapes, and angular upstroke in the “k”. The flourish at the end and the final flick resemble known characteristics of his authentic signings.

Forensic Ink and Substrate Evaluation

• Ink Absorption: Upon close inspection, the ink shows appropriate dispersion into the fibers of the paper, suggestive of a felt-tip or similar ink pen using a moderate pressure stroke.
• Line Weight Variation: The signature features dynamic shifts in line thickness and visible tapering at both the beginning and end of strokes. This is inconsistent with autopen or factory print processes.
• No Toner or Glossiness Detected: The ink lacks the powder-coating signature or shine associated with laser print reproduction.
• No Ink Pooling or Blotting: The ink’s flow appears evenly distributed but manually executed. The pressure variation seen across vertical and horizontal strokes is consistent with human dynamics.

Individual Signature Analysis

• “Love” Inscription: The word “love” appears written in a more relaxed style than the signature below. It has individualized slanting, natural variation in spacing, and fluid pen dynamics. The stroke boundaries are sharp yet subtly inconsistent, typical of a live hand-written inscription.

• “Mick Jagger” Signature:

• Initial “M”: Strong vertical entrance stroke and looping return—high fluency likely from repeated signing behavior. Slight shakiness is visible, but irregular enough to suggest human hand rather than mechanical tracing.

• Connective Flow: The transition between letters “ick” is smooth but not mechanically perfect—there is pressure reduction around the “k”, ending in a lighter stroke, likely from pen lift or fatigue.

• “Jagger” Segment: The “J” is tall, and the “gg” loops are tight and slanted to the right; consistent with authentic stylings.

• Terminal Stroke: A pronounced upward flourish ends the signature, breaking contact with the substrate. Subtle pressure variation further indicates a live execution.

• Final “x” Stroke: Stylized with irregular stroke strength—likely a hand-drawn embellishment. It does not exhibit symmetry or mechanical balance, which would be expected in copies.

Collective Signature Analysis

• The holistic view of the inscription and signature arrangement, spatial orientation, and ink flow patterns suggest a singular writing session using one writing instrument.
• The varying style and rhythm between the name and the inscription “love” are typical of authentic, casual notes.

Red Flags

• None Detected:
• No indication of mechanical reproduction techniques (no halftone patterns, inkjet dot matrices, or vector tracing artifacts).
• The signature does not match any known autopen templates (e.g. uniformity across known facsimiles used for fan mail responses).
• No inconsistency in ink distribution or unnatural fluidity suggestive of overlays, scanning, or duplication.

Conclusion
After forensic examination, no technical signs of reproduction methods were found in the presented signature. The presence of strong line weight dynamics, natural tapering, uneven stroke execution, and fluid variation in pressure align with freehand human-created autographs. While provenance is not established from submission context, and due to widespread forgery risk for Mick Jagger, a slight grade penalty is warranted in the absence of verifiable origin or certification trail.
