Snap On tools Metal Sign Collectable - Very Unique Aviation Airplane. It has a Gulfstream sticker on it as well as Rolls Royce buttons in the corner ( although they might have been added to the sign) . I have never seen anything like it before. It's not perfect flat kinda has some waves to it. Also some scratches as well. Overall tho - it’s super cool. It looks like it’s made out of steel or thick aluminum. Feel free to contact me with any questions .
