I'll publish photos of the pochade box later on my blog, Anto. Since you're so keen, here are some photos of a painting expedition by bicycle:

This looks like something I could paint!

There's even an appreciative audience. In the bicycle basket the complete kit of easel, black bag with paints and tools, and shooting stick to sit on.

Set up to work. The paints in the bag are oil bars, which is pigments (colours) in wax. I don't use a palette with oil bars, just holding the oil bars in my hand and digging out as much as I want with a silicon colour shaper, which saves on cleaning brushes.
