I received this at a fair about 10 years ago. It's a non-sale notebook from a Cremona violin maker. I've been to various fairs since then, but I've never seen it. I think it's quite valuable. I've kept it carefully as part of my collection, but there are some initial scratches. Please understand this before purchasing. There are 40 pages of staff paper.
