At this point in time this was a damn good drawing of one of my hapless algebra teachers. I actually remember doing it in class since paying attention never mattered much for me anyway. Good guy.
I had some leftover watercolor on my palette and added it to some old sketches. This is the Fabriano sketchbook with the red cover. I keep finding it on sale at hobby lobby. It's perfect for using on a plane, or just in general.
