Das Stundenbuch: Ross Vat. 94. Edited by Luigi Michelini Tocci. Belser Verlag, 1983.
This tiny book of hours is housed in the Vatican Library, one of the most notoriously inaccessible collections (though now digitized). You might not get into the Vatican Library to see Ross Vat. 94, but you can have an exceptionally detailed facsimile of it in your collection, along with the companion text, both housed in the original clamshell protective box.
Overall, NEAR FINE condition, with some slight sunning to the label of the clamshell.
