Vintage Button Booklet
One social media site I belong to is called The Vintage Village. It is a Ning community site, for those of you familiar with that. Many of the members have vintage or antique shops (hence the name), but others do not and are collectors or just interested in the subject. Members have their own "page" and can post photos and links to stuff they sell, whether on Etsy, Ruby Lane, Zibbet, or other websites.
Today this caught my eye, posted by an Etsy shop by the name of Quinsippi Mercantile, who specializes in paper ephemera.
It is a 1969 revised edition of the booklet published by the National Button Society.
Here is the link if you would like to see more photos and details about this treasure.
