Fragments of a book of hours, possibly French, late 15th century

Possibly the final leaves from a French Book of Hours, this fragment contains the hymn Gaude pia magdalena (f. 1r) . The Collect is on f. 1v: Largire nobis clementissime pater for S. Mary Magdalene. The Anthem, Supernus hospes intravit follows this, and then [Verse] O beata Martha. Oremus is before the Collect, but the leaf ends here and the prayer is missing. On the second folio (f. 2v) there are some 18th century notes/scribbles where the name Gerbier is repeated. The 2 folios are still held together by the imprints of their original binding.
