Brian, sorry for the delay in answering your question. The center is the same medallion as you have. The medallion can be a stand alone item for sure. The collage piece can also be a stand alone item without issue. Or as in my case, both pieces were combined to create this third option.
The collage part is a laminate print. Very nice with many subtle details. I could remove the center metal piece and the same image is underneath. the problem with doing this, it would leave a small hole where the attaching stud comes through the laminate board.
I have been Sylvia Pecota's artistry is just amazing for sure.
