It's funny you should say that; I didn't see anything at the time, except the spaces between the heads, but now I see the green and the pink, the two people walking alone, the happy family and the grouchy looking girl. There's the beginnings of a photograph, but I don't think it works- that said, I don't believe that there's anything I could have done about it at the time, because I wouldn't have seen whatever was there....
