This poster is made to look classic, but it is actually from 2009. It has running Sonic, the famous checkered pattern...but Metal Sonic is looming in the background with a caution-stripe. Metal Sonic is nearly abstracted as it is shown so large. With the fan photo at right, you can see there IS line art for his body too & bolts background. The classic Sonic logo becomes part of the design (note matching colors) at the bottom. This was made by GE Entertainment. 

In the galary it is in an actual home. You can see the large size, cloth material, and plastic bars at the top and bottom. This extra shot also shows that there is line-art body detail to Metal Sonic in the background, & that the engine interior is yellow. A fantastic poster for Metal fans!
