This sign sold as part of the Jim's Forever Collection at Mecum Las Vegas for $17,700. Jim owned a Harley Davidson shop in my neck of the woods and was a motorcycle and memorabilia collector for more than 50 years.
How did Jim get this sign? Well a local guy and his buddies from my home town decided to road trip it out (over 27 hours one way) in his custom van to watch the Snake River jump. These guys were well known to always be walking a bit on the wild side. Well, once the whole jump thing was over, they decided to take a memento back with them so they grabbed this sign, loaded it in the back of their van and drove back home. These guys were customers of Jim's Harley Shop so at some point Jim acquired the sign from them. 49 years later $17.7K!
That local guy that led this escapade is now in his mid-70's and in a nursing home after leading a very hard life. I'm guessing he remembers that day like it was yesterday.
