A bottle opener promotes the GREEN BAY AND WESTERN LINES.

Now here's a unique little Green Bay & Western Lines promotional item� a bottle opener!

I'm not sure how old it is, but I'd guess it might have been made in the 1950s, when the Western Refrigerator Lines reefers carried the GREEN BAY AND WESTERN LINES lettering on their car sides.

It certainly saw some use! It's worn at the top right where you would hold it when opening a bottle.
