UDON's SF25: The Art of Street Fighter is a huge, 448 page tome filled with well over 1500 drawn and painted illustrations.
SF25 consists of numerous sketches, promotional art, in-game artwork, box art, marketing splash art and even never-before seen illustrations over 25 years of the game. Many are designed from well-known Capcom-affiliated artists such as Aikman, CRMK, Shinkiro, Daigo Ikeno, and Kinu Nishimura. Additionally, you'll find artwork used for Super Street Fighter IV by Polygon Pictures.
Artwork is not the only content within SF25. UDONhas translated commentary and interviews from Capcom artists, giving you an inside look into some of their inspirations, favorite pieces, and how they felt about contributing to the expansive Street Fighter Universe.
