How did Alli Mohammed acquire the photograph of Sai Baba that he is famous for delivering?

Chapter 41 of the Sai Satcharitra provides Alli Mohammed's own account of how he obtained the photograph. He explains that one day, while wandering the streets in Mumbai, he came across a merchant selling various beautiful pictures of saints, sages, and holy men. As he looked through the collection, Sai Baba's portrait particularly appealed to his heart, its attractiveness surpassing all the others. Since he already loved and worshipped Sai Baba, he became eager to possess the image. As he narrates in the chapter, he paid the price in cash, brought the portrait home, and hung it on his wall for his daily joyful darshan, having great love for Baba.
