The sculpture, which sits beside the Diana Princess of Wales Memorial Playground is the work of children’s book illustrator Ivor Innes.
He spent two years – 1928 to 1930 – carving “Little People” upon an ancient oak tree trunk that had been found in Richmond Park and relocated to Kensington Gardens (and in 1930, with his wife Elsie, published the children’s book, The Elfin Oak of Kensington Gardens).
The characters depicted include animals and fanciful creatures such as a gnome called Huckleberry, a series of elves including Grumples and Groodles and a witch named Wookey.
The hollow, incidentally, had been presented to The Royal Parks by Lady Fortescue in response to an appeal run to improve facilities in line with a scheme by George Lansbury (among other things, he also founded the Serpentine Lido).
Now a Grade II listed structure (and well protected by wire mesh), it has a few pop culture associations – among them, the fact that it appeared on the cover of Pink Floyd’s 1969 album, Ummagumma (the head of the band’s lead singer and guitarist David Gilmour can be seen projecting from the trunk).
Meanwhile, in 1996, Spike Milligan – long a fan of the oak – was the face of a successful campaign to raise funds for its restoration.
Announcing the Grade II listing in 1997, then Heritage Minister Tony Banks noted that the oak sat alongside the late Victorian fascination with Little People and complemented Sir George Frampton’s statue of Peter Pan (also located within the gardens).
“Together the two sculptures make Kensington Gardens very much the world capital of fairies, gnomes and elves,” he reportedly said.
