I am so glad to see The Queen continues her participation in this wonderful tradition and appears as glorious as ever at 92.
By the way, given her age, she gave the specially minted coins, The Royal Maundy, to 92 Seniors chosen because of their service to church and community.
Plenty of photos, a video, and some history of the Maundy may be found at the Daily Mail. (Yes, I know some hate the Daily Mail. But it is hard to beat them when covering royal events.)
May your Triduum and Easter be blessed and glorious as well.
