Chamishah Chumshei Torah [with the five megillot and haftarot]...and Mezukak Shivatayim. Amsterdam, at the press of Kaspar Steen. [1702]. Especially rare. Unicom?
[1] 299 leaves [missing the conclusion], 17.5 cm. Chamishah Chumshei Torah with nekudot and te'amim, five megillot and the haftarot for the entire year with an individual title page. One of the few books printed by Kaspar Steen.
The book is listed by the Bibliography of the Hebrew Book according to this copy! It's missing its conclusion, the leaves after the haftarot for Yom Kippur, but we have no way of knowing what's missing. Not in the National Library and, to the best of our knowledge, not in any of the large public libraries in the world. [There is one other known chumash with a commentary and Yiddish translation, but this chumash does not have a commentary or translation.] 
New, deluxe half-leather binding. Aging stains. Professional restoration to a tear on the first title page, and replacement paper mounted in the margins of solitary leaves. Fine-very fine condition.
