Verification for Michael Tilson Thomas | Item # 1340
Autograph Authentication – Michael Tilson Thomas
Confidence Grade: A
Overview
This analysis concerns a 1977–78 season program signed by Michael Tilson Thomas for a performance by the Buffalo Philharmonic Orchestra. The autograph features a personal inscription in blue ink addressed “To Ronny – with best thanks,” followed by the signature.
Following comprehensive forensic analysis using a 10x simulated magnification methodology, the signature presents all indications of being an authentic, freehand inscription done with a period-appropriate writing instrument. The nuanced variations in stroke pressure, letter formation, and pen dynamics strongly suggest live, manual execution.
Candidate Identity (Investigative):
- Michael Tilson Thomas – High Confidence
Signature form, flow, and inscription style match known exemplars from the mid–late 1970s, particularly in the angularity of “M,” distinctive “T” crossing angle, and the stacked rendering of “Tilson Thomas”.
Forensic Ink and Substrate Evaluation
-
Ink Type and Application:
-
Appears to be a blue ballpoint pen, which is consistent with the 1977 context.
-
Strong pressure variation particularly at the start and finish of the descenders and ascenders indicates authentic manual pressure shifts.
-
Ink absorption into the paper fibers is uneven, consistent with older ballpoint technology and human pressure inconsistency.
-
Substrate:
-
Standard-weight matte program paper consistent with concert literature from the mid-1970s.
-
No signs of ink bleeding or modern reproduction techniques like toner sheen or pixel-based rasterization.
-
Other Observations:
-
Minor indentation visible under magnified inspection in some parts of the strokes further corroborates physical pen-to-paper action.
Individual Signature Analysis
-
Inscription (“To Ronny – with best thanks”):
-
The inscription exhibits natural variation in spacing and pressure.
-
The flow of the cursive “with best thanks” segment contains spontaneous line quality and hesitation-free motion, which would be difficult to replicate mechanically.
-
Variable spacing between words is indicative of a live inscription.
-
Signature (“Michael Tilson Thomas”):
-
“Michael” shows a flowing cursive entry and distinct backward-leaning “l,” typical of Tilson Thomas’s mid-career hand.
-
“Tilson Thomas” is stacked vertically, an idiosyncratic but documented stylistic signature trait.
-
Letter joins show non-mechanical micro-wobble variation consistent with genuine penmanship.
-
Ink line tapering at exit strokes confirms lack of autopen tool usage.
Collective Signature Analysis
- The inscription and signature demonstrate consistent ink tone and pressure parameters, indicating they were executed at the same time with the same writing instrument.
- The rhythm and fluency across all words support the theory of a single, uninterrupted signing session.
- Signature structure aligns with known authentic samples from Michael Tilson Thomas during this period.
Red Flags
- None Detected:
- No evidence of autopen, photocopy, inkjet, laser print, or factory-reproduced characteristics.
- No pixel-level duplication.
- No anomalies in substrate-to-ink interaction.
- Inscriptions do not exhibit signs of tracing, halting, or artificial spacing.
