#TradeStories Tanvir had a small shop in Old Dhaka. One day, suddenly a foreign tourist came to his shop, holding a brooch with a strange design. He said, โThis is a hundred years old. What can you give in exchange?โ Tanvir offered his handmade wooden boat. The tourist laughed, took the boat for the brooch. A year later, while searching for the history of that brooch, Tanvir discoveredโit was a memento of a famous explorer. That day, he didn't just make a trade; he touched history.
