This book is a large-font reprint of the 1938 original. It was written by Columbia University graduate, mining expert, and California historian Ernest Abram Wiltsee, who was a collector of covers. (A cover is the name stamp collectors have given to what most people call envelopes.) The original limited-edition of this seminal work was only 500 copies; this copy plays an important and unusual role in the field of United States postal history.
