Note 1: The hologram example shown in 12-11.8 (human face) is
not a synthetic polymer button. It is the same hologram example shown in the NBS
Synthetic Polymers Handbook, reference 2 but was misidentified as explained by
Jocelyn Howells in reference 3. The example shown here is actually a glass disk
with a hologram film applied to the back behind which is a glued plastic shank.
A clear epoxy coating applied to the rim and back resulted in the
misidentification.
