Michael Shapiro is the founder and CEO of Ketubah.com, the world's leading publisher of artistic Jewish wedding contracts, and a worldwide lecturer on historical and contemporary ketubot. For nearly three decades he has helped shape the development of contemporary ketubah art by guiding both influential and emerging contemporary ketubah artists and by freeing a wider range of artists of the need to master the text themselves. His ketubah publishing innovations include cutting-edge archival quality printing, laser cutting on demand, and an online tool to submit and verify all Hebrew names on the contract. Shalom Sabar is professor emeritus of Jewish art and folklore at the Hebrew University of Jerusalem and the author of more than 265 publications exploring Jewish art and the material culture of Jewish communities in Europe and the Islamic East, including The Art of the Ketubbah: Marriage Contracts from the Library of the Jewish Theological Seminary.
