There are 10 rows or 8 buttons, each with a handwritten number and other marks and notations on card.

They are sewn on and back has a lot of messy knotted and overlapping thread.

I think most are original to this sample card, although there are probably some replacements that previous owners filled in missing spots.

The original buttons have a sort of brass box shank with 4 holes in a domed rather than squared opening.   More than half have this type of shank, others have traditional brass loop shanks, and some with molded shanks, and there are 3 that are 2-hole sew-thru buttons in the bottom row.  

Smallest buttons are 3/4" and largest ones are 1-1/8".

There are some wonderful buttons including a bird, a crown, beautiful lacy glass, lots of flowers and geometrics.  There are 4 square buttons and one large oval, the other 76 buttons are round.

The heavy cardboard card is 11-1/2" wide x 16" high.
