I am not at all sure what happened here, some sort of chance effect of a double exposure I guess, but I'm glad it did. As it is, it appears as though the woman at right is levitating above her found companions, her body leaning against the shop window and her head looking rather as if punching right through it!  And with the perfect sort of grimace and lay of the hand to amplify the effect, while the overlaid edge of her coat highlights the hugging hands of the women to her left. Also visible near the feet of our levitating woman is what looks to be a hat shop sign. 

5 1/2" x 3 1/2". Good condition, with a bit of black paper stuck to the photo at top right and bottom left.
