I made the above watercolour for the opening ceremonies of a new plant for the firm Stahl. They make the highly specialized materials that look like leather and are used in car dashboards. Imagine what they have to endure! The lab is very well designed (not by me, but by a colleague, Sjoerd Gort).
The painting was presented to the client a few weeks ago.
I only forgot to make a picture of the final result, this is the nearly finished version.
