Marveaux signed for Toon on Friday.
He told nufc.co.uk: "This is a dream move for me and I'm very happy to be joining such a great club. As soon as I signed I couldn't wait to phone my parents in France and tell them the news. I've already sent them both Newcastle shirts!"
"Newcastle United are one of the most well-known clubs in France and have a great tradition. I saw quite a few of the games last season and thought the team did very well in their first season back in the Premier League."
