Alpine Antics

Alpine Antics (1929) is a Looney Tunes/Vitaphone animated short released under the Warner Bros. banner. Under the 1909 Copyright Act, works published between 1928 and 1963 required a copyright renewal in the 28th year to maintain protection. While the film was originally registered for copyright on the release date (Copyright Reg No. MP1002, dated December 23, 1929), no renewal record exists in the Stanford Copyright Renewal Database or the Library of Congress Catalog of Copyright Entries for the appropriate window (1956–1957). A search of the 'Film Superlist: Motion Pictures in the U.S. Public Domain' confirms that many early Vitaphone and Looney Tunes shorts from this specific period fell into the public domain due to non-renewal by Warner Bros. Consequently, the work expired into the public domain in the United States upon the conclusion of its first 28-year term in late 1957.
