Little May McAvoy, who was the leading lady opposite Jolson, had red hair. Red is not sensitive to orthochromatic stock, so a girl with red hair looked like a deep brunette when she was photographed on ortho.

She’d be a brunette on this side of the door and a blonde on the other side of the door. Yeah, we were solving problems and creating new ones.
