This is another (older) pencil board. It is meant to help you with the checkered globe style Sonic 3 special stages.
The front has a nicely shaded stock art, with the famous "Do it when you can" quote and some (somewhat redundant) names and logos. The back is more interesting as it features maps of all 7 special stages, as well as a 'key' to reading them. It is interesting to see their layouts flattened into squares instead of on spheres. It's rather curious slogan "Let's Get Blueballs!" can have other meanings in some cultures...which is rather unfortunate.
