Thanks to Double T of Black Cats Manor, I am happy to confirm that my photo "Makar Sankranti" was indeed published in the new Lonely Planet coffee-table book, A Year Of Festivals.
Lonely Planet requested a larger version for a half-page shot, but I was unable to access my photo DVDs which are, I think, in a trunk in Rishikesh.
The down side of perpetual traveling.....wonder if those photo DVDs are still any good.
Here's where you can purchase the book or a calendar:
