China.
By the looks, I would say the (Young) man sitting is in His 50's, & the 'Man of Years' standing is 70+!
Man of Years has a Very Victorian Dress Style & Manner
Were as the Youngster has a more Edwardian look about Him! (Firm, Self-Assured & Looking Straight at [through] the Camera)
So, I would Guess the Date of the Photo to be C1910
