a sacred gift to the American Bahá’i Community... lock of Baha'u'llah's hair

The Guardian in 1937, sent a sacred gift to the American Bahá’i Community through Millie. This was the lock of Baha’u’llah’s hair that had been preserved by the Greatest Holy Leaf, to be placed beneath the dome of the American Bahá’i Temple. She presented the gift during the 1938 National Bahá'i Convention mounted in a silver frame, the first of many sacred gifts from the guardian to become part of the National Bahá’i Archives.
