Adrian Powell is a British freelance illustrator responsible for creating the box art for the very first Lemmings video game. He also illustrated numerous Lemmings spot illustrations that appeared on the front and back of that first release of the game. Lemmings is the only box art Adrian painted; he did not paint the box art for any subsequent Lemmings games.
Fun Fact: When Adrian first saw the Lemmings video game prototype, each Lemming was essentially just a ping pong ball. Soon after his visit, Adrian created the first Lemming, which is the large character on the box art that is looking off in the distance.
