La Gerusalemme Liberata di Torquato Tasso

A little volume from 1822 that we picked up for £1.50 in Lyme Regis last weekend. It was sewn on two small sawn-in cords, laced into boards lined with printer's waste: what caught my eye was the advertisement for the Encyclopedia Britannica on the back board, published between 1820 and 1823. Trying now to work out a good way to replace the missing front board and stabilize the back board attachment without obscuring the now visible printed matter.
