Poster

Posters are a type of tapestry hung to walls that depict an image of a person or elements. They are often used for promoting events or people, or even ideals.

Usage
During the 1960s, posters were placed throughout the Soviet Union. In addition, the M21 drone featured a poster inside the canopy featuring a Japanese woman.

During the 1980s, there were posters meant for recruitment for either the Soviets or for various Private Forces, as well as some posters that had a more risqué element to them. Mother Base also featured some posters on the Command Platform featuring an idol singer named Paz. Venom Snake, the leader of Diamond Dogs, the PF that owns Mother Base, frequently used these posters in missions, either to have enemy soldiers mistake him for a superior officer and salute, or otherwise ogle the posters and distract them long enough for him to escape or take them out.

Posters were also utilized on the USS Discovery, the Big Shell, as well as in Eastern Europe and South America.

Behind the scenes
Posters made their debut in Metal Gear Solid 2, as an easter egg feature for both the Tanker Chapter and the Plant Chapter. Pressing the Action Button will have a boing sound effect that implied that Solid Snake had an erection. Posters also appeared in Metal Gear Solid 3: Snake Eater during the beginning of Operation Snake Eater as well as during a scene where Naked Snake hides Raikov's body inside of a locker. The woman on the poster in the former was Yumi Kikuchi, a gravure model as well as an old acquaintance of series creator Hideo Kojima. The latter featured a poster for Raiden as he appeared in Metal Gear Solid 2, an indirect reference to the similarities between Raikov and Raiden (as Raikov was deliberately made in Raiden's likeness due to Raiden's controversial reception in his debut game). Yumi Kikuchi's posters also appeared in Metal Gear Solid 4.

In Metal Gear Solid V: The Phantom Pain, posters had a more major role in the game, acting as a form of camouflage that can be applied to the Cardboard Box.
