This is the kids' version of the Speed Demon design from Full Throttle Saloon. The shirt is a nice bright orange. The graphic, which is identical to the adult version, has the words "Full Throttle Saloon" in white and "Speed Demon" in black in large letters above a graphic of a biker with "Established 2000" and "GET ON THE THROTTLE" behind him and "Sturgis South Dakota" below. The only difference being that the kid version is printed on the front of the shirt. The back is blank.
Also available in adult sizes (slightly different color) https://fullthrottlesaloon.com/products/speed-demon
