This was created as a prop for a vintage vehicle. A custom “permit” was designed incorporating a state seal and custom text. This was designed to look as if it could have been a permit used when the vehicle was in service. This was printed in full color on engineer grade reflective material.*
The red printing is translucent giving the finished piece a red glow when hit with light. The entire piece is reflective except for the black text which is opaque and blocks the reflectivity.
*Engineer grade reflective material is too modern a technology to be truly accurate for the early 1960’s.
