Any guesses about the origin of this sign? It looks to be lithography or silkscreen print on silver metallic paper, and mounted on an art board substrate. Overall condition is pretty good with minor blemishes. The artist initials are LH in the skunk art. The back has a signature that reads "J. Scott."
The only other thing I can think of is that I live in Chico, CA and the former SR-71 pilot, Brian Shul, was retired in nearby Marysville. There's also an airport in Chico with some older aircraft and a museum. I've listed this item for sale at auction on eBay.
