In 1973, The City of Orange was looking for ways to celebrate its one hundreth year. Inspired by the Street Fair of 1910, it was decided that for their centennial celebration, Orange would have the Orange International Street Fair (OISF). The Fair was so successful that it has become an annual tradition during Labor Day weekend. Location Old Town Orange Plaza. Each year the Street Fair has a theme driving the designs of the branding. This year’s theme is “Globally Good”. It is a place where friends, families and neighbors get together to experience a wide variety of food, music and dance from cultures and ethnicities throughout the world.
