MASON CITY - A blue sky with white clouds and pink and purple flowers will greet future tenants of apartments above Central Park Dentistry in the Parker Opera House. The 130-year-old mural is located in a dome on the third floor of the building. It was recently restored by Mason City artist Jan Kostka. "I'm very pleased," she told the Globe Gazette. "It will make for a feeling of ethereal - looking out on a nice day in Iowa." The second and third floors of the building are being remodeled into 13 apartments. When the project started, owner Jay Lala said he knew the mural had to be restored. "It's unbelievable; just gorgeous," Lala said. "She basically replicated it. It's actually the only remaining remnant of the opera house."
