One of my first logo designs is this one, which was accepted in 2002 and used by my high school (T.C. Ziraat Bankası Balıkesir Science High School) for several years.
The logo is a combination of first letters of the schools abbreviation in Turkish (Ziraat Bankası Fen Lisesi) with a torch placed on top symbolizing education.
Colors were chosen by the school administration.
