Dog Music Box

This is a music box that I found at a flea market. There are no markings or numbers anywhere and I have no idea where to start. It hangs on the wall and is a pull string music box. There are dogs inside in a school room setting (they are kind of three dimensional, like a pop-up book). When you pull the string, the teacher dog backs up, the song "Everybody Loves Somebody Sometime" starts to play, and he starts to move forward back to his original spot. I believe that it is french, because in the corner there is a little dog wearing a dunce hat that says "Ane" which means donkey. The woman that I bought it from said that she thinks it's from the 1960's, but that she researched it and could not find anything about it. She had refurbished it with a new frame and new material on the outer sides. All of the inside is still in it's original state. I know that this is probably not exactly an "antique" yet, but I would still greatly appreciate your help. Thank you in advance.
