20 Photos of Hollywood Actresses Posing in Shamrock Patterned Dresses for St. Patrick’s Day in the 1940s

In the 1940s, it was a common publicity practice for Hollywood studios to release holiday-themed pin-up portraits of their starlets to keep them in the public eye.

For St. Patrick’s Day, these “cheesecake” photos typically featured actresses like Maureen O’Hara, Maureen O’Sullivan, and Angela Greene posing with festive props or in themed attire. While many of these portraits were in black and white, they often showcased dresses with bold shamrock prints or accompanying giant shamrock cutouts to signal the holiday.
