Q: 17 colour illustrations,leather bound with a brass/copper plate on front depicting israel. the book is actually called haggadah'
A: As a previous answer said, the Haggaddah is the story of the Exodus that is told on Passover. There are many, many editions available (almost every Jewish family would have several to use at the Passover meal, called a Seder), so your book is not inherently rare. The only question is how much the special binding is worth. I think I have located a book that is similar or identical to what you have, so click on the source to compare it. If you want to sell, go to a dealer in Judaica or old books and ask them to value your book, but don't expect it to be worth a forture. Good luck!!
