This is the model of a book preserved at INAF - Palermo Astronomical Observatory, Historical Library, titled “Atlas céleste de Flamstéed”. It presents a missing page of the tav. 10 and on the flyleaf anteriory there is the ex-libris of Giuseppe Piazzi, the first director of the Observatory of Palermo from 1790 to 1826.
Ex-libris, or a bookplate, is a small print inside the cover of a book to express ownership. Books were considered highly prestigious objects to own and so, some of ex-libris are decorated with fabulous images.
