Anyway, here's today's offerings: California.
Auto registration plate with a surround plate.
Cool surround plate typeface!
From 1999 - very old. Note the open top "4" California uses.
Much more readable than the closed top "4" almost every other state uses.
The open top version should be mandatory for all road signs, too.
19 August 2014 - This one is ancient - from the late 1970s or early 1980s.
Note the "Art Deco Revival" design and typeface at the top of the plate.
Also the plate number begins with the repeat cycle numeral "2".
