Autograph Authentication – Ruth Bader Ginsburg

Confidence Grade: A (Most Likely Authentic)

---

Overview

Upon high-magnification forensic review of the handwriting and ink on this photograph inscribed “For the gang at Grandma’s / Cheers! / Ruth Bader Ginsburg”, the signature and inscription reveal multiple indicators of genuine freehand authorship. The ink-flow characteristics, stroke variability, and micro-level artifacts appear consistent with a live signature rendered in blue ink using a ballpoint or felt-tip pen. No visual artifacts associated with autopen, printed reproductions, or photocopy methods were observed. The overall stroke fluidity, entry/exit dynamics, and pressure variation support an attribution of authenticity.

Candidate Identity (Investigative):

• 1. Ruth Bader Ginsburg – High Confidence: Letterforms, rhythm, rightward slant, and capital “R♐B♐G” structure match documented exemplars with high congruence.
• No plausible alternatives rank above low confidence. Conclusion: Proceed under confirmed identity as Ruth Bader Ginsburg.

Forensic Ink and Substrate Evaluation

Ink Type & Behavior

• The signature and inscription appear to be written in a blue ink that exhibits moderate absorption into the paper fibers. This absorption style is more consistent with traditional ballpoint or light felt-tip pen, not printed or laser mechanisms.
• Minor ink feathering seen at pressure points indicates variability typical of real-time pressure and human hand motion.
• No signs of pooling, over-saturation, or uniform pigment dispersion were detected—key markers that would suggest mechanical autopen or inkjet printing.

Surface/Substrate Interaction

• The underlying medium appears to be matte photo stock with a fine tooth, allowing visible ink interaction without excessive bleeding.
• No gloss or halo effect consistent with laser printing was found.
• Pressure variation across inscription aligns with expected behavior on this photo-textured substrate.

Individual Signature Analysis

Signature: “Ruth Bader Ginsburg”

• Stroke Pressure: Variability observed, especially at downstrokes in “R”, “B”, and trailing letters in “Ginsburg.”
• Line Quality: Confident, lightly shaking entry to “Ruth” matches known late-career signatures. Micro-waver appears human and not mechanical.
• Flourish Characteristics: Subtle upward flare in final “g” echoes hand-signed stylistic elements in known examples.
• Pen Lifts and Rhythm: Natural pacing and pen lifts observed between name components (“Ruth”→“Bader”, “Bader”→“Ginsburg”), matching typical inscription behaviors.
• Inscription Complement: “For the gang at Grandma’s / Cheers!” rendered in consistent ink and pressure with individualized spacing, suggesting a pause-and-write freehand style.

Collective Signature Analysis

Ink Consistency Across Content

• Both the greeting inscription and formal signature exhibit identical ink hue, weight, and stroke width.
• Sequential variation in angle, pressure, and flow confirms the presence of distinct human-motion dynamics, not replicated mechanical strokes.
• Cohesive handwriting tone and rhythm affirm that the note was inscribed and signed by the same hand in a natural sequence.

Red Flags

None of the typical indicators of autopen, reproduction prints, or mechanical signatures were observed. Specifically:

• No pixel-perfect stroke congruence.
• No “micro-wobble” or alignment duplication.
• No evidence of toner, inkjet patterning, or laser-burning features.
• No edge halo, feathered mechanical shallow-fiber prints, or toner granularity.
• No “flattening” of pen pressure near stroke terminations.
