Create a photorealistic promotional poster featuring a 1930s special forces soldier wearing a vintage gas mask. The soldier should be in a dynamic pose, perhaps holding a period-appropriate weapon like a Thompson submachine gun. The background should evoke a 1930s war setting, possibly with trenches, barbed wire, or old military vehicles. The gas mask should look authentic to the period, with intricate details like filters and eye lenses. The soldier's uniform should also be historically accurate, complete with badges, patches, and other insignia. Dramatic lighting should highlight the soldier and create a sense of urgency and action. Text elements promoting the game, such as the game's title and tagline, should be prominently displayed in a font that complements the vintage aesthetic,<lora:oldjpposter:0.55>
