If you're a fan of obscure-but-awesome NES games like Taito's Little Samson and Irem's Metal Storm, this compilation might be worth checking out. Utata Kiyoshi Artdot Works, recently published by doujin group Game Area 51 in Japan, showcases sprite art and character sketches from games featuring Kiyoshi's designs.

Also included in the collection is art from the Strider spiritual sequel Cannon Dancer (released in the west as Osman), which has seen a resurgence in popularity lately due to Strider designer Kouichi Yotsui's recent return to game development.

Other featured works include Takeru's Cocoron and Nostalgia 1907, along with Mitchell's Funky Jet and The Karate Tournament.
