That man's almost smiling! She ain't, though

Man's long collar with the rounded points (round points!!!

) started just after 1900 and the lady's pompadour hairstyle just a little before that. Both were replaced with different styles just before the war. But as we can't see much else, stylewise, I can't give you much of a narrower window. Call it around 1907, give or take 5 years? Not very good I'm afraid, Carol

Do we know where Williams & Williams were located?
