Of course! Postcards were first discovered in the 19th century, but it took some time to gain popularity. However, any vintage these things value a lot; the same goes for these cards. Besides, the value depends more on its condition. For example- If the vintage or antique cards are in all good condition with no discolouration, tears, or other damages, it costs more. However, age is another factor to be considered. In the year 2002, the oldest postcards were sold for $50,000 on London Stamp Exchange. Besides, the painting on the postcard was posted in the 1840s.
