Anathomia ossium totius humani corporis.

Woodcut of a skeleton (355 x 250 mm).
This wooduct was first published in Paris in 1493 by Ricardus Helain (sometimes Hela) and is usually considered the earliest known fugitive sheet; there is also a 1493 Nuremberg edition. Helain's name and the date which appeared in a rectangle at the upper right is in the Leipzig edition replaced by a scroll, crediting "Helandt" and giving the printing place and date of the woodcut's production; Stöckel's printer's mark is in the text block at the top left of the sheet. Another difference between the two editions is that in the later copy, the skeleton has only four toes on each foot.
Morgan sheet with watermark of a bull's head, surmounted with a tall cross with a snake twirled around the shaft (18.4 x 5.8 cm, centered on a chainline), similar to Briquet, no. 15374, produced in Italy and used in Austria and southern Germany from the late 1480s. NNPM
