In response to my question about the source of our logo, I got the following response from Arlen Comfort.
Hi Sanda,The Green Party Tree (logo) was drawn by Arden Farey. He was an industrial designer by profession until forced to retire because of multiple sclerosis. He had no use of his arms or hands so he used a paintbrush attached to a mouth-stick to produce his artwork.
He was Green Party member when he drew the logo while a patient in the Menlo Park VA, where he died 6 years ago. Much of his work was politically motivated and some was published with then current newspaper articles.
This link has many pictures of Arden’s artwork including the GPSMC tree andof him drawing with a mouth stick. (near the bottom)– Arlen
