Q: My mother was given this book (Rubaiyat of Omar Khayyam) and I found it going through some of her things. Could you tell me anything about it?

A: This book is part of the Waistcoat Pocket Series.

The ten book series was published between 1906 and 1921. These miniature books came in several formats and sizes. They all were originally sold within a labeled box. An example of a box is shown here.

Covers of limp lambskin, velvet calf and boards have all been seen.
