I found some lovely images today from a book called Old and New Japan from 1907. The artist's name is clearly shown in the front of the book as Montagu Smyth (no 'e' in Montagu) but I can't find anything about him on the web. I did find a Walter Montague Smyth (with the e) who died in 1965 which would make his work still in copyright but I really don't know if it's the same man.
Lovely pictures, aren't they! I'm not sure about their copyright status so if you want to use them, please do your own research on Montagu Smyth first.
