Initial I for a Martyred Saint - Master of the Montepulciano Gradual

Recently, this clipping of a Saint being martyred failed to sell at an auction in Germany.  I was able to obtain it in a post-sale offer. As luck would have it, I reached out to Dr. Bryan Keene to ask their opinion of it and to my surprise, Bryan had previously written about the artist while working as an associate curator at the Getty Museum in LA and was even familiar with the leaf in question.

A blog post on the Getty's website does a better job of explainig the history of this artist than I can, but for a TL;DR version, the artist has historically been associated with the Master of the Antiphonary of San Giovanni Fuorcivitas but many recent scholars including Keene believe it is by a different hand and have began naming the artist Master of the Montepulciano Gradual.

Below is a list of sister clippings taken from the Getty post, followed by images of the different clippings I have managed to track down.  One thing I find interesting about the grouping is the distinct borders on some of the leaves, with a handful only having a plain black background, whereas the majority tend to have a colored border with white embelishments.  I've noted the plain black border initials with an asterisk in the list below.  Photos appear below in order.  If no photos currently available it is noted.
