Our Gospel of Mary (P.Ryl. 3 463) is currently on loan to the British Museum exhibit Egypt: Faith after the Pharaohs. In the video below you can listen at me talking about the importance of papyrus findings for the understanding of early Christianity (or better: early Christianities), and above all you can see the fragment itself as recently restored by the excellent John Rylands Library conservation department.
I have written about this fragment offering my own translation in a previous post.
