This is a short story to be sold online. It takes place in the Mekong Delta during the Vietnam War shortly after the Tet Offensive. The Tiger Bar is a bordello. The principle characters are military intelligence agents stalking a Viet Cong operative. The image must draw attention to the description and provoke a purchase.
The design elements that can be used as source material are the old Vietnamese flag for South Vietnam, bamboo, beautiful Asian women, Huey Cobra helicopters, the U-6 Beaver de Havliand single engine, fixed wing, observation aircraft, camouflage patterns from uniforms of the era. These are source elements and you need not use all of them, just some of them. The title "Last Call At The Tiger Bar" needs to be at the top of the image or clearly readable within it and "A Story by Francis Hamit" needs to be at the bottom of the image. This is a story with lots of sex and violence.
