i have a kicker sticker about as long as a seegulls wingspan. made for the top of your windshield. (eyebrow sticker) also i have an atomic sticker that would cover your back window.
Those are called steal me stickers. Guys at the shows only put them on for the day. When you advertise people will steal your stuff. Ebay has many vinyl stickers.
