As seen on the back panel of Decepticon Transformer Barricade (the police car) in the live-action movies.
This is not a simple brush script font (as is sold by other vendors, including Amazon). This is a painstaking recreation of the actual decal, hand-tweaked from high-definition photos to be as close to the actual artwork as possible (we've included a reference picture of the original star car used in the film).
Available at full-size 30in (to match actual police cruiser graphics) as well as 24", 18" and 12" lengths.
