How rare is this Union Oil Speed & Power Curb Sign with the Medal of Honor & Gold Medal , Panama - Pacific Exposition caption on the bottom of the sign. I have seen a few of this type of Union Oil curb sign with just Speed & Power but never one like this one and what would the value be. I would say it is a 8 out o 10 as far as condition and is good on both sides.

The Panama–Pacific International Exposition (PPIE) was a world's fair held in San Francisco, California, U.S., from February 20 to December 4, 1915.

that is the 2nd one of those I've seen, SUPER RARE .. ...

IMO - value: 4k+
