ChatGPT Replicates Cartoonists' Signatures on AI-Generated Art

ChatGPT has begun generating "New Yorker-style" cartoons that include the replicated signatures of real cartoonists, leading to confusion and concerns about artistic authenticity and attribution. One such cartoon, depicting Dolly Parton and Tim Curry at heaven's reception desk, went viral on social media platforms including Twitter, Facebook, Instagram, and Bluesky, garnering tens of thousands of likes. The AI-generated image was signed with the pen name "BLOPER," the recognized signature of New Yorker cartoonist Brendan Loper.

Brendan Loper stated that he did not create or sign the cartoon, which was initially posted to Facebook by a fan who had asked ChatGPT to produce a "New Yorker-style cartoon." Loper reported being contacted by numerous individuals, including his twin brother and strangers via email and direct messages, inquiring if the AI-generated image was his work. He described the experience as "very surreal." For cartoonists, signatures have evolved beyond mere bylines; in an era where digital art is frequently shared out of context and without proper licensing, signatures serve as a crucial watermark, linking an illustration to its original creator. Loper emphasized that his signature acts as a "certificate of authenticity" for work he shares online, signifying ownership and acting as a personal brand.

Loper is not the only New Yorker cartoonist whose signature has been mimicked by ChatGPT. Reports indicate that dozens of similar AI-generated images featuring the signatures of other prominent contributors to the magazine are circulating in online forums. This trend highlights a growing challenge for artists and publications in distinguishing between human-created and AI-generated content, particularly as AI models become more sophisticated in replicating stylistic elements, including unique artistic signatures. The ability of AI to accurately reproduce these personal marks raises questions about intellectual property, copyright, and the potential for misuse in creating deceptive or unauthorized works. The New Yorker itself has not publicly commented on the AI-generated cartoons or the replication of its contributors' signatures. The situation underscores the evolving landscape of digital art creation and distribution, where AI's capabilities are increasingly blurring the lines of authorship and originality.
