The Library of American Comics Essentials series was expensive to print and largely avoided by collectors when released, but now are quite collectible.

From the publisher:

In many ways Tim Tyler's Luck is the prototypical adventure strip, launching three years before Hal Foster's Tarzan and six full years ahead of Terry and the Pirates. Creator Lyman Young combined an exuberant young cast and exotic locales into a frothy mix that turned millions of readers into armchair adventurers. The never-before-collected strips in this Essentials volume represent a transition point in comics history, showcasing the seminal work of superstar artist Alex Raymond. Lyman Young hired Raymond as an assistant in May, 1932, and throughout the strips in this book Raymond took on increasing responsibility for the drawing until he essentially assumed the complete art duties. It's in these strips that Raymond developed the prototypes for Flash Gordon, Dale Arden, and Jungle Jim, the characters he would create right after his stint on Tim Tyler's Luck, as he embarked on a career that would change comics forever.
