Pin up tattoos have been a popular choice for decades, with designs that range from classic to modern. The term “pin up” is derived from the phrase “pin up girl”, which is a woman whose photo is pinned up on a wall. This phrase dates back to the early 1900s and was popularized during World War II. While the pin up girl originally was an image of a woman that soldiers would pin up on their walls, the term has evolved to include a variety of styles and designs.
