LOU paper postcards are a type of postcard that were popular in the early 20th century. The term "LOU" is short for the French word "Lettre d'Ouverture Universelle," which translates to "universal letter opening." LOU paper postcards were unique in that they had a fold-out flap on the back, allowing the sender to write a longer message than would fit on a traditional postcard. This feature made them particularly popular for sending messages to friends and family. The LOU paper postcards were often printed on high-quality paper with intricate designs and images, making them highly collectible today. Many collectors focus on acquiring LOU paper postcards from specific countries or regions, or those that feature specific themes, such as holidays or landmarks. If you're interested in collecting Lou paper postcards, it's a good idea to do your research and familiarize yourself with the different types and styles of postcards that are available.
