The dead wax carries the original Golden Records matrix number, R58 and, presumably, cut dates as follows:
A-side: 4/9/51 (9 Apr 1951)
B-side: 4/28/51 (28 Apr 1951)
This album was intended as a tour promo item for dealers, to be given away free with every full-price Ray Conniff album purchased (see Billboard story).
