What should I look for to determine the authenticity of 'premium' Star Wars comic art?

Examine the artwork closely for consistency with the artist's style, look for signatures and any identifying marks, and compare the piece to published versions to ensure it matches. Research the provenance (ownership history). Obtain a Certificate of Authenticity (COA) from a reputable source or the artist themselves, if possible. Consult with experts or other collectors if you have any doubts.
