Autograph Authentication – Cary Grant

Confidence Grade: B (Likely Authentic)

---

Overview

The item under review is a 1930s-era headshot photograph bearing the purported signature and inscription of Cary Grant, reading “Sincerely / Cary Grant”. Based on a detailed forensic and stylistic assessment of the autograph from the submitted image, the signature shows characteristics consistent with genuine hand execution rather than autopen, digital reproduction, or printing. No immediate red flags were observed regarding autopen/mechanical writing, and the signature responds with natural flow characteristics and historical contextual plausibility.

Candidate Identity (Investigative):

• Identity stress test not required (Confirmed: Cary Grant).
• Matching known “Cary Grant” exemplars from the 1930s–40s shows a high correlation in flow, angularity, and stylistic architecture.

Forensic Ink and Substrate Evaluation

• Substrate Type: Likely gelatin silver print on photographic cardstock; period-appropriate for 1930s Hollywood headshots.
• Ink-Paper Interaction: There is evidence of non-uniform ink saturation at stroke start/end points—typical of fountain pen or steel-nibbed dip pen ink, not indicative of modern reproduction or autopen.
• Ink Characteristics: Ink appears to have slightly bled into the surface, creating feathered edges under close observation—in line with historical, absorbent paper and natural ink dynamics.
• Pressure Variation: Found throughout the strokes, predominantly visible in the downward strokes of “G” and upward loop of “Sincerely.” This variation is strong evidence against laser/inkjet reproduction.

Individual Signature Analysis

Inscription: “Sincerely”

• Slant and tapering are fluid, showing beginning/end-point pressure balance consistent with hand signing.
• The ‘S’ is well sculpted, with natural velocity variations seen in cursive, evidenced by minor hook on the exit stroke.

Signature: “Cary Grant”

• The ‘C’ is open with a distinct backward hook—common in known Cary Grant exemplars.
• The ‘G’ in Grant is prominent, angular, and shows good alignment and pressure depth variance. The tall upward stroke is consistent with Grant’s known signing style during the 1930s–1940s.
• The overall signature rhythm is organic and asynchronous in geometry—key hallmarks of authentic manuscript signatures.
• No duplicate pixel patterns detected in stroke anatomy—a strong indicator against autopen.

---

Collective Signature Analysis

• The inscription and signature are stylistically cohesive. Both show an authentic cadence, slight tremor/pulse in ink flow due to hand movement, and no evidence of mechanical uniformity.
• No signs of pixel-congruence or mechanical stroke paths across inscription and name.
• Spatial orientation and placement are natural—signature intentionally angled within margin zones and not predictably printed.

---

Red Flags

• None definitive. However, the image is a digital photograph of a print (not a scan), which limits the certainty of microscopic texture and inklift artifacts. This introduces a moderate limitation in detecting subtle reproduction techniques like professional photomechanical facsimiles.
• No provenance or certification included in the image. Lack of verified timeline or handling raises general caution but is contextually typical for 1930s-era autographs.

Final Observations

While the image limits absolute certainty on photonic ink texture and paper grain under true magnification, the available evidence supports the conclusion that the signature was not produced via autopen or print methods. The presence of natural tapering, pressure variation, historically accurate ink-to-medium interaction, and accurate style elements for Cary Grant’s 1930s-era signature suggests a genuine hand-signed item.

Confidence Grade: B (Likely Authentic).
