Details of print Antieke liturgische muziek op vellum

Unique: a vellum leaf with handwritten prayer and the music and text of the Gregorian hymn "Tibi Christe, splendor Patris". Inscribed on both sides in black and red ink. The leaf has obviously passed through many hands through the centuries, and has been repaired as well. Top right is a hole in the text as well as smaller tears on other places.
