About the picture of Eugene in his nightshirt: I thought Solanaart provided the streetscape, but she referred me back to you. I love that streetscape, love it to bits, adore it! Is there a link you could refer me to, or any other information? I want to have it printed so I can stare at it to my heart's content.
Hi, and thanks for asking! The painter is Willem Koekkoek (LOVE the name!), a Dutch 19th century artists. The name of the painting is simply "Dutch street scene by a canal", as it seems. He did a lot of similar works.
Here's the painting on artnet: http://www.artnet.com/artists/willem-koekkoek/dutch-street-scene-by-a-canal-1Ywku_XkA2AjvXJ9qLdthg2, and here on flickr: https://www.flickr.com/photos/amber-tree/22665599587 , where I scrupulessly grabbed it from.
