Gaming Historica/Retro Art Gallery | Sonic Chaos Concept Sketch | Greg Martin [Part One] (Patreon)

I was researching some Sonic things and find out about Greg Martin who died in 2013. Very sad. He was the artist who made all the Sonic cover in the west for consoles like Sega's Mega Drive and Master System. Here is a sketch art for the Sonic  Chaos game on Master System and Game Gear that was never used! I think this is very interesting. I will share some more of Greg Martin lovely  artwork in this series soon. 😋
