Incredibly rare first edition of a Franciscan music pocketbook by Leopold Wolff, an organist at the Franciscan convent Ad Olivas near Cologne. It contains lyrics and musical notes, including a chart depicting the notes and keys. The book would be especially fascinating to anyone interested in the history of music. Leather with two clasps, one defective. Former monastery library book with sticker on spine and stamp inside. Boards rubbed. Binding firm. Typical darkening and foxing of paper due to age. Three pages bear stickers meant to serve as bookmarks. Text block well-preserved and clean. An outstandingly preserved copy. (56)
