The following description was prepared by William Gross:
"Ein Ya'akov" is a famous Jewish book, here in an edition printed in Amsterdam and bound in a magnificent parchment binding. This sort of parchment was prepared by rubbing vellum with a horn and then painting it, a technique developed and used by one binder in middle 18th century amsterdam. In this example, the binding is stamped on each side with a biblical hero, in one case, king David and in the other the "akedat Yitzchak", the sacrifice of Isaac. Both of these images are derived from 17th century biblical engravings by Mattheus Merian.
