This boot (Paul McCartney's boot after he shrinks), originally a Help! prop, ended up at the bottom of John Lennon's garden at his home Kenwood on the St. George's Hill estate, Weybridge, Surrey, England. Here's a photo of John relaxing in his yard next to the boot.
This great website about Lennon's house Kenwood has many stories and details about the home as well as this picture of the supposed location of the boot on the the grounds. Kenwood Lennon
