.It strikes me if one looks on the Internet, you can probably find quite a lot of papyri divided up into nice rectangular pieces ready for framing like the Harvard Jesus' Wife Fragment. Here's a tastefully framed example from a well-known New York gallery.
And to the left an unframed example, but notable for its regular shape and the very cursive writing.
If you are interested in buying such items, here's the address. Sadigh Gallery Ancient Art Inc. 303 Fifth Avenue, Suite 1603, New York, NY. 10016 US. Maybe he can find another Jesus' wife papyrus for a private collector. All items come with a guarantee of authenticity, maybe Professor King's collector should have come shopping here.
