LA CENTER — The halls of La Center High School are like wings of an eclectic museum, where artwork from various periods, of different styles and motifs, mingle.There are presidential photos shot by Pulitzer Prize winner David Hume Kennerly in a hallway. There’s a sarcophagus mask from Egypt behind a Plexiglas case in the library. And, hanging atop the school’s front entrance, a massive sculpture representing the solar system expands across the ceiling.Art and drama teacher Don Landes-McCullough is the school’s archivist, its curator and its biggest cheerleader.But after a 30-year teaching career, he’s calling it quits. Landes-McCullough will retire at the end of the school year.Looking closely at a model of the HMS Victory — the oldest naval vessel still in commission, the replica of which is displayed in the school’s library — Landes-McCullough reflected on a decades-spanning career spent bringing students closer to art.“There’s so much detail in here,” he said, referencing the art displays in the library, and elsewhere in the school, “because everything here was chosen for a reason.”For decades, Landes-McCullough was the point person for making those decisions. In 2005, he contributed $13,500 worth of art to the school. A lifelong art lover, self-taught in various media, those who know him say he isn’t above spending his own time or money on artistic pursuits.
