Found another example, but no date info.; RARE ANTIQUE LEVI STRAUSS & CO.MEDIUM OVERALL BUTTON
Cool.
I have a good feeling about these.
At first glance I thought early 70's psychedelia.
But after a second glance I'm leaning more toward earth 20th century.
Both references to this include the word "rare" (black button and the website).
Anyone sign up to the website that nhbenz posted as to get a price?
I will get some size reference pics up soon, hearing all this got me itchin to go thru my button cans. I may have more and even have old rivets. Thanks everyone I havent been this excited about finding out about something for a while. I love this site!!!
