The Oklahoma State Capitol was completed June 30, 1917. As part of the Oklahoma State Capitol Centennial, a collection of items from present-day have been collected for a centennial time capsule. Keep Oklahoma Beautiful had the opportunity to include a letter for the capsule, and hopes to convey to future generations the importance of a sustainable, beautiful Oklahoma. Our hope is that when this letter emerges in 2117, it will look upon an even more sustainable, beautiful, and clean Oklahoma. You can read the full text of the letter enclosed below.
