A rare book (one of two in existence) at the Grolier Club. I think it was printed by Jensen. It used to be a smidge bigger, that’s not the original binding. (Also, those are not my fingers) Printed on vellum.
From the Butler Library. This book, the Epistole Devotissime de Siena, (1500AD) has the first ever printed italic text. This is the fronticepiece, or first (and highly decorated) page.
