OPTOMETRIC RECORD BOOK

A record book, wherein to record optometric examinations, is an indispensable adjunct of an optician’s outfit.

The Keystone Optometric Record Book was specially prepared for this purpose.  It excels all others in being not only a record book, but an invaluable guide in examination.

The book contains two hundred record forms with printed headings, suggesting, in the proper order, the course of examination that should be pursued to obtain most accurate results.

Each book has an index, which enables the optician to refer instantly to the case of any particular patient.

The Keystone Record Book diminishes the time and labor required for examinations, obviates possible oversights from carelessness and assures a systematic and thorough examination of the eye, as well as furnishes a permanent record of all examinations.

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.)
