If you like it, then it is worth something to you, and it is really the most important aspect of collecting,
But as far as its value goes, sadly yes, it is not worth much. A friend of this forum, Matt, sold an original French affiche for $1k a while back (that's 47x63in, or 120x160cm). That seems insane to me, but when people collect a certain genre, actor, director, title, they want it all, so it could explain it. I don't think a large one should be worth more than $200, but that's me. A smaller version sold for $130 at emovieposter. Yours is a reprint of that one.
Sorry,
