The symbols of the seal stand for the name of the school: the acorn and oak leaves for Oak, the three small trees for Park, the wavy lines for River, and the trees again for Forest. Thus, they represent Oak Park and River Forest.
The words on the seal are in the Greek language. In English, they are “Those Things That Are Best.” They mean that each person should strive for the best things and high ideals. It is hoped that the motto will have this meaning for each teacher and student.
The seal, worked in orange and blue upon a deep blue background, serves as the school flag. The flag was designed by students in art classes.
The seal has been registered for copyright and cannot be used except for official school business. It was originally designed by Mr. Lee M. Watson, a teacher in the school, and was first used in 1908.
