Pin-ups were a popular cultural phenomenon in the mid-20th century, featuring images of attractive models or actresses usually in a provocative or suggestive pose. Synonyms for this term could include "cheesecake," "girly pictures," or "eye candy." Other related terms might include "glamour shots," "vintage erotica," or "burlesque imagery." Though the heyday of pin-up culture has long passed, many of these terms continue to be used today to describe similar types of images and content in various media. Whether seen as empowering or objectifying, the pin-up genre remains a fascinating and complex aspect of popular culture.
