Just some interesting information I came across, about Lesbia Kadleigh:
Lesbia Kadleigh was a muralist, though the only work of hers I can find online is that above Waterloo Station Gate:

I cannot find an actual announcement of Lesbia's death, but Google AI says she died 1997.
Lesbia was born 1916, daughter of the eldest son of Sir William Selby Church, Bt.
