Answer
Frans Hals was frequently misidentified as the creator of Judith Leyster's paintings. Leyster, a talented Dutch Golden Age artist, often signed her works with her initials, "JL," which were easily mistaken for Hals's signature, "FH." This misattribution persisted for centuries, overshadowing Leyster's own artistic contributions until her work was rediscovered and properly attributed in the 20th century.
