However, there are a few possible explanations:
* French Influence: "Marie-Louise" is a French name, and the style of frame is generally considered French in origin. The name might have simply been applied to the frame due to its widespread use in France during the 19th century.
* Style Association: The Marie-Louise frame is known for its simple elegance, with a smooth, rounded profile and often a gilded finish. This style might have been associated with the aesthetic preferences of a particular person or era named Marie-Louise, which led to its adoption as a descriptive term.
* Popularization by a Manufacturer: It's also possible that a specific manufacturer or art dealer popularized the term "Marie-Louise" for this type of frame, and it became the accepted name over time.
Unfortunately, without specific historical records or documented evidence, it's impossible to definitively trace the origin of the name "Marie-Louise" for this picture frame style.
