1. General Information Artist: Elvis Presley Title: Blue Moon / Just Because Format: 10" Shellac, 78 RPM, Single Label: RCA Victor Catalog Number: 20-6640 Release Year: 1956 (August) Country: USA 2. Description This record captures a pivotal moment in the "King's" career. Both tracks were originally recorded by Sam Phillips at Sun Studios in Memphis (Blue Moon in August 1954; Just Because in September 1954). When RCA Victor purchased Elvis's contract from Sun in late 1955, they acquired these legendary masters. This 1956 release marks the very first time these recordings were issued to the public as a single. "Blue Moon" is celebrated for its haunting, ethereal atmosphere and Elvis's unique falsetto—a stark contrast to his more aggressive rockabilly numbers. This specific copy was manufactured at the Hollywood, California pressing plant, identified by the stamped "H" in the runout. 3. Condition Disc (Visual): Excellent (E) Labels: Very clean with sharp silver printing. Minimal spindle wear around the center hole. No writing, stickers, or major tearing. 4. Notes for Collectors First Edition Status: This is a True First Pressing. It features the original black RCA Victor label with "Nipper" (the dog) at the top and the "New Orthophonic High Fidelity" branding. Hollywood Pressing: The "H" stamp in the deadwax confirms this originated from the Hollywood plant, which is often sought after for its high production standards during the mid-50s. Matrix Details: Features the 3S suffix on both sides, representing the early stampers used during the initial 1956 production run. 5.
