Wien: Artur Wolf Verlag, 1919. Unique numbered edition of 500; on handmade paper. This portfolio of tipped-in engravings after the originals, comprises 24 loose sheets, as issued. These copper engravings were created as relief engravings based on those found at the Wiener Hofbibliothek. Four page introduction by Dr. Karl Kloss. The portfolio is in good shape, with some rubbing to edges. Inside, the sheets are clean, and the work is complete; but most of the plates have been slightly folded over at the top edge when the portfolio has not been carefully closed over the years. 295 x 270 mm (11½ x 10¾ inches).
