I found this cool site that you can design your own tin sign in any color and a lot of sizes. Sam wants a picture of piper on a parking tin sign.
Know he has to choice what color he wants.
The picture has to be at least 300 dpi to make a good quality picture. They will even send back a proof before it is ordered. You can choose from parking tin signs,license plate tin signs and even street tin signs. They can also put wording on any sign you choose.
So go check out custom designed tin signs.
