The Charlton-based lenticular specialist produced the four-panel 5x2.4m display for the flagship store. A second display was also created for HMV's Bond Street store.
According to Mark Roblett, director at Riot of Colour, the display is possibly the largest 3D lenticular display ever made in the UK.
The entire project took two weeks from file delivery to the final product with many hours spent rendering "enormous" digital files for printing.
"It’s always nice to have an opportunity to push the boundaries of lenticular technology to new levels," he added.
