Hey man! Where you been?
This piece is a Chinese or Japanese traditional style watercolor mountainscape - with the obligatory monks walking the precarious path to the temple.
My concern about it is that the signature is in Romanized characters - not kanji. To my mind that means it isn't very old or it's a knock-off or both.
My first reaction was the signature said "Tony". But it could easily be "Jong".
I didn't find any pieces with similar content. But it would look great in my office.
