'I was very interested to make some drawings of scientists even though I have to confess that my knowledge of the subject is very limited.  However, probably not many people have my awareness of the importance of the bucket in scientific experiment, some hints of which I'm happy to share with you here.' - Quentin Blake, November 2020

Taken from a large collection of line drawings in several A3 sketchbooks, drawn using either biro or Pentel pen.
