Can you tell me the story behind the Sai Baba portrait that Dixit saw at Mirikar's house?

The portrait of Sai Baba that H.S. Dixit saw at Mirikar's house in Ahmednagar has a special history detailed in Chapter 51. This particular photograph was deeply cherished by Megha, a devoted disciple of Baba, who worshipped it with great reverence as if it were Lord Shankar himself. The glass on the portrait had broken, so it had been sent from Shirdi to Ahmednagar with Balasaheb Mirikar for repairs. After being fixed, the portrait was kept covered in Mirikar’s drawing room. Chapter 51 notes that after Dixit's travel plans with Madhavrao were finalized, Balasaheb unveiled the portrait. Because Balasaheb was staying longer for a horse show, he entrusted the repaired portrait to Madhavrao to take back to Shirdi.
