Zwolle: [Johannes de Vollenhoe], 1479. An attractive leaf, taken from Bonaventure's Sermons. Printed in black with red highlighting of capitals and key letters. Printed to both sides of the leaf, in two columns. Area of light staining to the bottom corner of the leaf (visible both sides) otherwise in excellent condition. The paper is chain laid paper, with a crude unicorn watermark. Although we have been unable to date / match precisely, the paper and watermark are very similar to some in the graphics arts collection at Princeton University, including one from Bruges dated to 1475 and another dated 1593. Very small damage to the edge where removed from a book. Slight marking to one side of the paper. 270 x190 mm (10¾ x 7½ inches).
