A big blanket!
This is one of those 'dye-sublimated' fleecey-fabric throw blankets. It's 1-ply (not stuffed) and the surface is fuzzy. It is 46x60 inches, so it's pretty big. It should be about $30 dollars, and you may be able to find it on Amazon in 2019. But where else is it?
This is a great blanket for fans, because it has so many characters all in one place. You can see Sonic Tails, Knuckles, Amy, Cream, Blaze, Shadow, Cheese, Rouge and Eggman there at the top. They are on a background that looks like Escape from the City's steep hill / truck chace level. The modern logo is pretty big in the bottom left.
Getting most of the gang together in the middle makes for a really colorful blanket to decorate a Sonic room.
