THE KEYSTONE
BOOK OF GUARANTEES OF WATCH REPAIRS

This book contains two hundred printed guarantees, and is handsomely bound.  Each guarantee is 31/4 x 71/2 inches, and most carefully worded.  Jewelers have discovered that the use of these guarantees is a most effective way to secure and cultivate public confidence.  We sell a book of two hundred for

  $1.00 (4s. 2d.), prepaid,

  which is one-third less than the price charged by others for a
  similar book.
