All the colored pictures of the trees are lost. I intended on giving them as gifts to my friends Louis Hoffman, Brent Dean Robbins and Shawn Rubin to commemorate some work we had done in psychology. I brought them to a conference and accidentally left them at the front desk in a cardboard tube. Realizing I left it there two days latter I called the front desk, they told me they openned the tube, looked at the contents, and deterimined it was junk. They threw the work out!
