If you go to the website to purchase tickets, you will find more information. " The Andrea Doria was the flagship of the Italia Line and a source of Italian national pride post World War II. On July 25, 1956, bound for New York City, the Andrea Doria collided with the eastward-bound Stockholm becoming one of history's most famous maritime disasters. Today the Andrea Doria lies at the bottom of the Atlantic in approximately 250 feet of water, 60 miles south of Nantucket Island, Massachusetts. It has dramatically deteriorated since it first went to the bottom. The plate will have an accompanying certificate of authenticity to certify that the artifact described herein was recovered by John Chatterton from the wreck of the Andrea Doria."
I hope this gives you more information and more interest in helping SUDS and the Academy of Scuba in it's fund raising efforts for the extraordinary veterans and servicemember's SUDS helps.
