This picture is just too sweet for words. I absolutely adore little Lillian's expression and how all of the light is focused on her face. you can tell that she's the center of attention (as it often is in families with babies) and the apple of her father's eye. It was a clear choice for my father's day lineup of pictures which I'm just barely getting in under the wire (this is the second of three fatherly photos that I've uploaded today).
It doesn't seem to have been sent but it's original owner (probably Ludwig's and Lillian's immediate family given that it's unsent) had the foresight to label it (and in legible handwriting too!). there's no date, but it looks like it was probably taken around the 1910's or so.
