Charles Darwin Signed 1876 Portrait Photograph Linen Rag Paper Autograph For Sale

An original portrait photograph of Charles Darwin, boldly signed by him in black dip pen and dated "1876." This remarkable piece offers a rare opportunity to own a tangible connection to one of history's most influential scientific minds.

1876 places this signature just three years after Darwin published The Expression of the Emotions in Man and Animals and near the end of his active scientific career. Signed Darwin photographs of this era are exceedingly scarce, and examples on linen rag paper—a durable, high-quality stock favored for archival photographic prints—are prized by collectors for both their longevity and provenance potential.
