Hi, I also received one of these postcards the other day. It is a little bit different though. It has a picture of the Carnival Victory on it. Also, the phone number is different - 1-855-468-0311. The real kicker though is that despite the picture of the Victory and the Carnival logo on the front and back of the card, part of the fine print reads "This promotion is not sponsored by or affiliated with Norwegian Cruise Lines." I didn't call the number but did a search on it and it is listed as being suspicious.
