This collection of 72 LP albums was produced by the Musical Masterpiece Society, MMS. They come in a nondescript cover, and all are 10" in diameter. The buyers were sent a catalog, and they would then order the music they desired. The album covers show varying amounts of wear and age, but the albums seem to be never used. We haven't looked at them all but we did examine several different titles. We have #2,4,5,8,9,11,14,15,,16,18,19,20,21,23A,24,25,26,27,30,31,32,35,38,40,41,42,43,44,46,47,48,49.50,52,53,54,55,56,57,59,60,61,62,63,64A,65,67,68,70,72,73,74,75,76,77,78,79,80,81,82,84,85,86,87,105,106,121,122,123,124,129,and 131.
