This is "Mass in B Flat (Theresienmesse)" by Joseph Haydn, in a paperback piano/vocal score published by Schirmer. This edition features the complete music of the mass, arranged for chorus and keyboard, with text in Latin. There are two scores:

1.) Condition of this paperback score is Very Good Plus, showing light shelfwear to the covers and no writing or other marks inside the score.

2.) Condition of this paperback is Very Good Minus, showing a moderate spine lean and a number of line pencil marks throughout the score. Please see my other vocal music listings.
