All are 7/8" litho buttons done in same identical style although those without Elvis photo are marked on the curl "Made In U.S.A." whereas those with his portrait do not have this text. The seven picturing Elvis represent all seven that we've seen over the years so we assume this is the total number issued. Titles are "Anyway You Want Me, Blue Suede Shoes, Don't Be Cruel, Heartbreak Hotel, Hound Dog, I Want You/I Need You/I Love You, Love Me Tender." The version with song titles represent nine of twelve known. Those included are "Ain't That A Shame, Blue Suede Shoes, Green Door, Heartbreak Hotel, Hound Dog, Love Me Tender, My Prayer, Singing The Blues, You'll Never Know." The three missing from this set are "I Want/Need/Love U, Rock Around The Clock, Rock N Roll." On these nine "You'll Never Know" has 1/8" rim scratch but the rest are NM displaying Mint. Largest number of the two sets we've ever been able to offer.
