This is a jointed Sonic party banner. CA Reed Co. did this as well. Usually this type of banner is made from cardboard letters that spell out 'happy birthday'. The banner SHOULD say: "Way cool Party" and has Sally and Tails in between "Way" and "Party"
Either way, this item is uncommon and curious! It's also one of the few purple Sonic items. CA Reed chose purple frequently, which no other merchandise really leans toward, for whatever reason. Photo discovered by Sonikkou-No-Uta, added info by Crystal Sonic Fan

NEEDED: a photo of the whole banner, spread out so everyone can read the phrase & see the art they used, send it in for credit, if you have a photo

In the gallary you can see the close up of the packaging
