Nettie Tobin & the "corner stone" for Chicago Temple

 Nettie Tobin kneeling by the stone which she carried as her contribution to the Chicago Temple in the very early days. 'Abdu'l-Baha chose it as the "corner stone" when He visited the site in 1912. The stone is now incorporated into the building, and serves as a special place for prayer and meditation.
