I have physical pictures; this was long before digital photography was a thing. Let me dig them out and, I guess, take pictures of my pictures to share. :-)

It was a small book by page count, four signatures of eight pages each if I recall correctly. The cover was couched velvet rather than leather (limitation of both knowledge and tools/materials). I got a private tour of the rare-books room at the Carnegie Mellon library where they allowed me to examine bindings, since you normally can't see that when books are displayed open behind glass. (Surprised me too! Pays to ask rather than assume.) All of their books had a lot more signatures, but I took other details of the binding (like how many cords and stitch size) from those exemplars. I was a young not-even-Maunche and probably made lots of mistakes, but it was a cool project and I learned a lot from doing it.
