Curiosa: Philadelphia

Found this morning a ms. note in pencil on the front free endpaper of a very much knocked-about copy of The Roman Actor (1629) by Philip Massinger:

Imperfect and poor -- my own dear sister did it up in this way. I taught her bookbinding and she rapidly excelled her master in this as in many things else --

Awww. That's so sweet. (No, really: "imperfect and poor" refers to the state of the bookblock, not the binding itself.)
