This is Reprise R-20,128, "Me and My Shadow", sung by Sinatra and Sammy, backed with "Sam's Song", sung by Sammy and Dino.

It is the only 45RPM picture sleeve ever produced by Reprise that features the entire Rat Pack. This single is highly desired by collectors. The picture sleeve has some ringwear, as shown in the photo, but no tears of any kind; the record would grade Excellent and doesn't appear to have been played.

Only one to sell.
