Auburn Six sign

It is a popular reproduction. I have a couple of them.

I found this in my grandparents basement and was curious if it was worth anything or just a typical run of the mill sign. My Dad grew up in Auburn, IL and we found this sign in his parents basement while cleaning out the house. I've always been a car buff (admittedly, never heard of Auburn Automotive until googling this sign), and really liked it. Will hang it in my kids room or basement, but wanted to share w/ the community.
