Pinup girl signs, also known as “cheesecake” signs, were a popular form of advertising during the mid-20th century. These signs featured attractive and often scantily-clad women in poses that were meant to be both alluring and attention-grabbing. They were often used to advertise products like beer, cigarettes, and gasoline, and could be found on billboards, in magazines, and on the sides of buildings.

Pinup girl signs were a reflection of the cultural values and gender roles of their time. These signs often portrayed women as sexual objects, and were meant to appeal to a male audience. They were also a reflection of the changing social norms of the mid-20th century, as traditional gender roles were challenged and more women entered the workforce.

Despite their popularity, pinup girl signs were not without controversy. Some people saw them as objectifying and demeaning to women, and they were often the target of criticism from feminist groups. Despite this, pinup girl signs remained a popular form of advertising for many years, and continue to be a nostalgicically-remembered part of popular culture.

Today, pinup girl signs are often seen as a vintage and collectible item, and can be found in a variety of forms, including posters, t-shirts, and other merchandise. Despite their controversial history, they continue to be a popular and enduring part of popular culture.
