Chesler (the "A" stood for "Anything") was a comic book packager and publisher. He operated a packaging studio more or less continuously from the mid-30s through 1953, and at times also operated as a publisher. In 1941 Chesler published with Dynamic Publications, Inc. From this point on, most of Chesler's comics would be branded with a logo proclaiming them the "World's Greatest Comics". In 1941-1942, this also identified each issue as "A Dynamic Publication". After just over half a year, Dynamic ceased publishing, he continued producing a few books through surrogates. The surrogate activity picks up dramatically in 1944, leading into Chesler's third major wave of publishing. In place of "A Dynamic Publication" these had "Harry "A" Chesler, Jr.". Junior, however, was the son of Chesler the publisher, a point of much confusion for latter-day comics researchers. This period lasted through 1946, after which the ongoing titles were continued in Canada by Superior Publishers through early 1948. Chesler continued to run his art shop, but no longer published his own comics after 1946.
