Pictures of Mardeen at work can be seen here.
According to a posting on the Second Harvest Food Bank Website:
"The mural shows workers in fields of fruits and vegetables as well as other colorful Watsonville-specific details. The painting was accidentally torn and so Gordon, who is a master embroiderer, first repaired the tear before restoring the paint. The mural was originally painted by Ralph D’Oliveira in 1979 when he was part of the Tortuga Patrol, a group of artists who were known for their role in the California Chicano movement. Another well-known painting by this group can be found in the Gilroy Apartments. Incidentally, Ralph and Mardeen were acquainted."
