The dashing young chap looks like Lyle in around 1908-12.Around 25-30 in that 'tache.how does that fit?
The other chap's wearing a smoking cap.The woman looks like a barrister,court official or similar but I'm not sure when women first occupied these positions.
The mans dress style could place this from the 1890's up to the 1920's.Some older chaps just refused to budge when it came to updating their wardrobe.
The plant stand looks Art Deco.
What sort of photo is it? postcard,snapshot etc.
