Is Ramzan's Sri Krishna picture fake?

Is Ramzan's Sri Krishna picture fake?

Recently on the Eid day, several public personalities and even politicians like Sashi Tharoor and Yogendra Yadav shared a picture that they claimed to have been drawn in the 18th Century.  In the now-controversial picture, Lord Krishna is seen "looking at the Eid moon with the Rozedars in Rajasthan".  

However, some credible voices have claimed that the picture was never drawn by a famous painter in the Medieval Era.  It's of recent origin, they allege.  

A History scholar has challenged the proponents of the picture to prove that it existed in the 18th Century.  There is no published reference of this painting from scholarly works or museum catalogues, she says.  

However, Dr. Dipankar Deb, author of a book titled 'Muslim Devotees of Krishna', counters the critics.  He says, "All those who are asking questions about "Krishna showing Eid Moon" picture. Read my book for further information. I have not said "Krishna is celebrating Eid". These are your words. Krishna is Supreme Lord. Everyone is subordinate to Him. Genuine seekers of the source, it is in my book."
