I have been privileged over the years to have been commissioned to work on several Hagadot . Two in my opinion  have stood out in their uniqueness and creativity. One is the Jerusalem Hagada, commissioned in 1999, and illustrated beautifully by artist
Yael Hershberg, using motifs from the architecture of Jerusalem. The second is the Moriah Hagada, a project by artist Avner Moriah, who in a visual delight of color has illustrated his Hagada with motifs from primitive Egyptian paintings. Both Hagadot have been reproduced in high quality facsimile editions. To view some pages of each click on the appropriate link below (and apologies for my poor, amateurish photography).
