Can someone transliterate this artist's name? This is a placard next to a work of art from a museum in Japan. I'm curious as to what it says—particularly, what the artist's name is. !enter image description here

The artist's name is Mitsuo Banba ( ).
The title of the painting is "Crossing the Yarlung Tsangpo".

Yarlung Tsangpo is the part of the Brahmaputra River that flows through Tibet.
