Autograph Authentication

Authenticating autographs comes down to knowledge/research with authenticators examining and comparing many thousands of signatures over years. It’s important to keep an extensive and comprehensive autograph database for comparative reference that spans a signer’s lifetime and signing circumstances. No two signatures from the same hand are ever identical. Signature styles evolve over time and often vary significantly when someone, as an example, signs a mail request at their desk vs. signing for someone in person when they are ‘on-the-run.’

In examining signatures, authenticators look at many things, starting with if the type of writing instrument used was available at the time. An autograph signed with a Sharpie before 1964 (when that marker was invented), for example, should raise a red flag.

A signature is compared to known examples for things like structure, shape, style, speed, spontaneity, slant, scale, size, instrument pressure and live ink vs. machine manufacturing via an autopen or laser copy or other type facsimile preprint.


Years of experience as a professional print manufacturer have given a keen perspective on print imaging of all types.
