The sculpture, named Pinewoof, was created by Gordano School’s graphics and reprographics technician Josh Williams and his wife Aimee, who designed and painted the piece.
The couple crafted the sculpture in their home studio for The Grand Appeal, the Bristol Children’s Hospital charity.
Commissioned by Pinewood Studios and sponsored by Bristol City Council’s Fostering Service, the design paid tribute to decades of cinematic history.
In a joint statement, Mr and Mrs Williams said: “We were given a brief by Pinewood Studios to capture the magic that happens there and to show subtle hints to the famous films and shows that have been made there over the years.
“It was lots of fun, especially getting to hide dinosaurs, aliens and spies all in one sculpture.
“Pinewoof is definitely the most detailed sculpture we have done for The Grand Appeal, and we spent hundreds of hours getting him just right.
“The most common response we got about Pinewoof was about how long people spent looking at the details.
“People especially liked all the hidden elements.”
Pinewoof sold for £20,000, contributing to the £2m raised through the trail’s charity auction.
The Williamses have supported The Grand Appeal since 2015.
Over the years, they have helped design four sculptures across three public art trails, collectively raising £59,500.
The Grand Appeal funds vital services, equipment, and research at Bristol Children’s Hospital.
