Unsigned artworks are some of the most challenging pieces to appraise. Without a visible signature, the work must be evaluated through its stylistic traits, construction, materials, techniques, and contextual clues—rather than by name recognition alone. Many unsigned works are decorative, but others may be valuable workshop pieces, circle-of-artist productions, or paintings whose signatures were lost through age or restoration.
