This is an old neon sign. With this sign, the tubes of glass are bent into a sort-of Sonic shape. The top in red spells out his name. Sonic is presented in a circle, with the 1 finger up / pose. However, because neon tubes can't be bent too far & they must loop/curve around in certain ways, it's not going to be exact. You can't really tell what color it's supposed to be because it's very hard to take a photo of something that's glowing quite brightly. Since this had to be a custom work, the sign was likely expensive. Notice that it's between 2 fiberglass figures. Even with the cropping, you can tell it's "hands on hips Tails" & classic Sonic from elsewhere on Retail Display Gear.
