This is an animation cell. It's a scene from Adventures of Sonic the Hedgehog (weekday Sonic) Here, he's shown at a sporting event similar to the Olympics, notice the olive leaf, roman head, & roman couch in the background. The speckling is meant to be spectators in the 'bleachers' area. AoStH was sometimes rather abstract. This could be from the Time Travel Arc...but do you recognize which episode this was from? Write in if you know! 

In the gallary is another animation cell from the Adventures of Sonic the Hedgehog (weekday Sonic) show. It is from the episode Prehistoric Sonic. It's another fairly special cell, as it comes with the characters Sonic & Tails on separate layers (its how the animation was made) along with the painted background. It also has the pencils for the scene underneath it all (not seen here) Unfortunately a bit, Tails' eyes aren't looking in the same direction for this shot so he seems a tad odd. Cells like this with 2 characters & the background are prized and harder to obtain.
