Antique Leather Bound Book

Got this old leather bound book here. It's got that classic vintage look with the ribbed spine and gold detailing on the edges. The cover is a mix of red leather and a greyish fabric or paper inlay. It's definitely seen some use and has that aged patina you'd expect from something this old. Not sure exactly what's inside but it looks like a cool piece for a shelf or a collector. Selling as is.
