I am currently writing a textbook for my students. I would like to request for your permission to use three of these cross-contour images in my book. Copyright acknowledgement will be given to you as (c) Robert Pollien. Is that alright with you?

The copyright for these drawings is retained by the students not myself. I cannot give permission to use them for publication and regrettably do not have contact information for the students.
