Eddie Cochran 45 Don't Ever let Me Go/ C'Mon Liberty Promo Record

Great vintage Eddie Cochran 45 rpm record of C'mon Everybody on one side and Don't Ever Let Me Go on opposite. Black and white Liberty label marked "Promotional Copy Not for Sale" with blue and white paper Liberty cover. The record itself looks beautiful -- I see just one very light scratch and some surface dust -- otherwise it looks completely unused. The paper labels show minor light soil. Cover has some creasing and a small hole and some heavier soil. I have no way to test records so I am not sure how it sounds.
