I had these custom-stamped metal replicas made based on my extensive collection of reference material for the original prop plates.
The colors are Pantone matched to original mid-1980s EHP \\\'Golden State\\\' California Prop Plates, and the yellow stripes actually go all the way to the edges as they are supposed to.
They also have the correct debossed/recessed outer border and boxes for the registration tabs, unlike all other replicas I have seen.
The registration stickers are high quality fade-resistant weatherproof vinyl.
