Can you elaborate on the history and significance of the specific Sai Baba photograph that was given to Kakasaheb Dixit?

The photograph given to Kakasaheb Dixit was highly significant and had its own history. Chapter 51 reveals that this was the same portrait that Megha, a devoted disciple of Baba, used to worship with great love, viewing it as a manifestation of the three-eyed Lord Shankar. The portrait's glass had broken, so it was sent from Shirdi with Balasaheb to Nagar for repairs. Having been repaired, it was kept covered in Mirikar’s drawing room. Its sudden appearance before Dixit, who was longing for Baba's darshan, was seen as a miraculous and auspicious event, making him feel that Baba himself had arranged this encounter to fulfill his heart's desire.
