Why does the cabuliwallah only have a hand print of his daughter and not a picture or letter?

The Cabuliwallah, a character in Rabindranath Tagore's story, only has a hand print of his daughter because he is a poor Afghan trader who has been separated from his family due to his arduous life and circumstances. The hand print symbolizes his deep emotional connection and longing for his daughter, serving as a tangible reminder of their bond in the absence of more conventional means of communication like pictures or letters. It highlights the themes of love, memory, and the sacrifices made by those who are separated from their loved ones.
