Here we're looking at the first Canadian digests in the modern (1935 on) paperback era. Published by Al Valentine's Adam Publishing Company in October 1941 the Handy Library imprint lasted two issues. Valentine was the publisher of pulps, some of which are listed on the back cover of Handy Library 1.
Both books are paperback originals with cover art by Wilf Long. Here is a cover by Long for one of Valentine's pulps - Uncanny Tales.
