April 21, 1922: Both Shrines of Baha'u'llah and the Báb were electrically illuminated for the first time

On the first day of Ridvan [1922], although Shoghi Effendi himself had left Haifa, the Shrines of both Baha'u'llah and the Báb were electrically illuminated for the first time, pursuant to arrangements made before the Master's ascension, but, again, supervised by Shoghi Effendi himself.
