Pages from the 1523 Bomberg Edition of the Alfassi being used as a binding

In the binding of a copy of Berit Avot by Rabbi Avraham Coriat, published in Livorno in 1862 by Elijah ben Amozag, I found 2 pages from the 1523 Bomberg Edition of the Alfassi being used as backing for the covers.
The Alfassi survived centuries only to end up buried in a binding.
The 2 leaves are from Masechet Ketuvot.
