Elvis Presley "Blue Moon of Kentucky" 1954 Sun Records 209 45 Single W/Push Marks - This 45 RPM 7-inch single is a rare example of an Elvis Presley recording on Sun Records, featuring Elvis' songs "Blue Moon of Kentucky" and "That's All Right". Identified as Sun 209, the song was famously recorded and released only weeks later in the whirlwind that was the beginning of Elvis' storied career. This is a "Memphis Pressing", as indicated by the push marks on the labels. These three marks were left by the record stamper indicating that it was pressed at Plastic Products, Inc. where Sun had records made in Memphis. The push marks indicate that this is an earlier vintage, as when Elvis' singles began selling big Sam Phillips started having records pressed at other pressing plants in California and Pennsylvania, which do not have the push marks.
