Looking through an old sketchbook today for something to post, I came across this which might be of interest to some. It's from a hardcover A4 book that I was using as a combination sketchbook/logbook in the last two years of my Painting degree. This page records some basic observations about a Rembrandt etching which was the subject of another post -- here. The related thumbnail of the rainy Savannah at lower left evolved into some abstract paintings about a year later. It's often amazing the length of time between the genesis of a thing and when it actually happens though to my knowledge I hadn't been thinking about it .
