This binding represents an early nineteenth-century bookbinding style: a smooth spine without raised or faux bands, half red leather binding, and the pattern of the marbled paper. There is a flexible hollow tube spine lining: the leather is not adhered directly to the spine of the text block but to the exterior of a paper lining that is hollow. This allows the text block to flex upward, away from the leather, when the book is opened, thus preserving the spine leather and providing much text block flexibility.
