Ariel Moscovici drawing/sketch

i have what appears to be a drawing/sketch with some paint also. In pencil it is signed Ariel Moscovici 75-6 in the bottom right hand corner. There is also 2/12 written in pencil on the lower left hand corner. It seems to be on some kind of paper and it is taped onto like a cardboard frame where the top piece opens and has like the empty window in the center so that when you close it you see the drawing. I found this in my closet. I bought it from a yard sale at one time or another and it has been in my closet every since. I forgot i had it. Any information would be great. thanks! sorry the pics weren't better.

Good
