The purpose of this section is to provide examples of black
glass buttons as defined in the NBS Classification Guide1
(Blue Book)
including one or more examples of each type in the listings and an example
that covers each term in the definitions. No attempt is made to illustrate
the wide variety of possibilities in the class/subclass categories.
Scanning and photographing
buttons have distinct limitations in the areas of perspective,
color, details, and dimensions. Thus, many buttons do not reveal
their true character and appearance in the photos or scans. When
uncertainty exists, ask a fellow club member or a dealer to show you
an actual example of the button in question.
A printable worksheet for black glass can be accessed with the link at
the bottom of this page.
