By Speedo, via Static Lookbooks website. Wish we had a better photo of it. It's such a beautifully crafted back.
We also tried to find a suit Speedo released in the 90's that had a photographic print of a pool shot underwater, which was some truly original photographic print work completed on swimwear. It was an awesome looking suit, but we couldn't find it anywhere online, and none of us have an old catalog. We gave up after Google made us view countless oiled up male models in their skimpies.
