Swasky, Catalan Wine Landscapes, 2014.
This blogger saw the book at the local public library. The publisher seems to be really small as it is hard to come by any information on the web. The English introduction can be found on this blog – then the text continues in Catalan. Further down in the same article, there is also a short video in English, showing the artist at work.
Another title by the same artist: Enjoy Gaudí, 2013.
More on the (mainly) urban sketcher Swasky on his website.
