half-stamp
A finishing tool consisting of a stamp identical
with or very similar to a half fleuron, pineapple,
etc. It is generally used for tooling compartments
at the edges of the frame in lozenge compartment
decoration. It is also sometimes used back-to-back
to form the lozenges in the center of the cover.
The use of the half-stamp was common in Northern
Europe and in England during the late 15th and
early 16th centuries. (250 )
