THE KEYSTONE BOOK OF MONOGRAMS

This book contains 2400 designs and over 6000 different combinations of
two and three letters.

Is an essential to every jeweler's outfit. It is not only necessary for
the jeweler's own use and guidance, but also to enable customers to
indicate exactly what they want, thus saving time and possible
dissatisfaction.

The Monograms are purposely left in outline, in order to show clearly
how the letters are intertwined or woven together. This permits such
enlargement or reduction of the Monogram as may be desired, and as much
shading, ornamentation and artistic finish as the jeweler may wish to
add.

This comprehensive compilation of Monograms is especially available as a
reference book in busy seasons. Its use saves time, thought and labor,
and ensures quick and satisfactory work.

Monograms are the fad of the time, and there's money for the jeweler in
Monogram engraving. The knowledge in this book can be turned into cash.
All the various styles of letters are illustrated.

Price, $1.00 (4s. 2d.)
