The Queen planting a tree in the San Anton Palace Garden, at Malta. She was offered the choice of two spades, a heavy type used by her father and grandfather to plant trees, and lighter type - modern. She chatted about them first, felt their weight then chose the lightest. The Duke of Edinburgh had a good look at the heavy spade, covered with plates commemorating previous plantings, then used the heavy type to plant his tree. May 04, 1954. (Photo by Daily Mirror).
