Thanks petermc61, powderdtoastman and spanishguitarmusic!
The guitar is of the Japanese Cortez brand. They built nice not too expensive instruments back in the eighties. I bought it used on a whim, but it's become one of my favourite instruments since then.
The Andantino is from the book shown in the video. It has no special explanations, but it's a nice compilation.
At the moment, I'm trying to become a decent steel-string fingerpicker, and to this purpose played the piece pn my dreadnought.
