Retouched "Thunderball" British Quad poster used in Malta. The bikinis were extended by painting over the original poster, similar to the Quads used in Ireland. Uncensored Quad as comparison below.
Thanks to Sylvan Whittingham Mason who shared the photo of the poster. She explains the story behind it in an interview with James Bond Radio Podcast, issue 13. The full interview with Sylvan is available here.
