autograph

An autograph is a person's handwritten signature, typically used to authenticate documents or as a personal mark of identity. It reflects an individual's unique way of signing their name, often appreciated as a collectible or a sign of endorsement. Autographs are commonly associated with celebrities, athletes, or notable figures, and they can increase the value of memorabilia. They serve both practical purposes—confirming authorship or agreement—and cultural or sentimental significance, representing a personal connection to the signer.
