According to a KP Blogcast, the posters had some similarity to a Paz artwork that also featured a similar signature on them. After taking the Paz posters down at Mother Base several times, a random Diamond Dogs soldier will remark "Hey, who keeps taking down my posters? Those cost a lot!" when Venom Snake returns to the base. The artist of the posters is Mino Taro, who is the illustrator of LovePlus, another game from Konami. His signature can be seen on the posters. He also appears in the end credits as guest illustrator.
