Whitman's Collector's Handbook , Revised and Enlarged , by Malcolm C. Salaman. 1921 . 375 (+1) pages.
From Alfred Whitman's Preface : " In the following pages an attempt is made to supply answers to some of the many questions that a number of
years' experience has shown to be those most frequently asked by amateurs at the commencement of their print-collection, and even by those who
have devoted some time and attention to the pursuit of their hobby."
