The classification of items as "antique" or "vintage" depends on their age and sometimes their rarity and cultural significance. Typically, an item is considered antique if it is at least 100 years old. Items from the 1920s fall into this category because they are over a century old, making them antique. Conversely, the term "vintage" usually refers to items that are at least 20 to 30 years old but less than 100 years old. Therefore, products from the 1920s are generally classified as antique rather than vintage.
In summary, 1920s items are considered antique due to their age, and they often hold more historical and collectible value compared to vintage items from the same era.
