Almost two weeks ago now a group comprised mostly of MPhil and PhD students and I took a trip to Dublin to see the Chester Beatty Biblical Papyri. There is a wonderful general display, where some of the joined up sheets of both P45 and P46 were a highlight - these really help to visualise the respective codices as a whole - P45 is comprised of a series of single sheet quires, whereas P46 is one large single quire.
Here is an image of a sheet from P45 (folios 13R - 14R, Luke 11-13)
Here is an image of a sheet from P46 (a bifolium featuring Romans 11 [fol. 15V] and Colossians 1 [fol. 90V]):
We were also able to take a closer look at a large selection of leaves from the NT papyri (P45, P46, P47), courtesy of Charles Horton.
