Some people will spend big bucks for fake signs, gees! The Cat symbol is not correct.

This sign is correct.

Good eye Gary-thanks!

Keep safe!

The market is flooded with all of these FAKE signs. Some are very nice though.
One of my favorite Caterpillar or maybe it was the Cletrac signs that keeps coming up for sale on Fleabay has a classic sellers description.

"My uncle used to work for Caterpillar as a crane operator and brought this sign home several years ago it has been sitting around and has scratches"

I love the aging process these "OLD" signs go through:
Chip the paint some and soak in salt water until it shows some age.
I haven't seen one yet that has a bullet hole or shotgun blast yet.  (LOL)
 

"They" keep on bidding! lol "A sucker born every minute!"

Sheesh! lol someone's got more dollars than sense!
