I thought I’d post a few pictures of the zippered, bonded leather “Christian Prayer” from Catholic Book Publishing Company.
The manufacturer’s item number is 406/23. The ISBN is 978-0-89942-424-8. catholicbookpublishing.com/products/101
I was surprise when I opened it to find that this version has chant notation. The title page says “Edition with Music”. I own the non-zippered large print version from about five years ago and it has no musical notation at all. My first impression of the zipper is that it is pretty heavy-duty. Time will tell but I am happy with the quality and feel so far.
