I have to agree with others that this is an early 50s (late 40s absolute earliest) photo. Are there any other options for who these people might be? I would say that it could not be a man born late 1890s and woman born 1905.

But if Nick is correct and this is Alice, which it must be as he has posted another photo of her, it cannot have been taken in the 50's. Unless Alice has a similar looking sister or cousin ...

It is difficult to judge the era with men's clothes and the guy in the mid ground could have been snapped yesterday looking at what he's wearing - it's fairly timeless. I really can't see the women in the background clearly enough to make a judgement on their clothes.
