Things and interior items that have gone out of fashion do not disappear without a trace. They become old.
It is important to remember that vintage is not just old and very old interior items. This is a cult thing; they have a recognizable, clearly expressed style of specific decades of the last century.
Due to increased demand, pre-1950s furniture in good condition are becoming more difficult to find, and more expensive to procure.
What are the components of the living room in the vintage style? Interior design should be created in a single style of a certain decade: leather sofas with a high back of the 30’s or a bright plastic chic of the 70’s.
