?JAI HIND? was the first commemorative post mark of Independent India, which was actually a war slogan of Netaji Subhash Chandra Bose, the Supreme Commander of the Indian National Army which was adopted by Free India as National Slogan of the country - Bharat

A close scrutiny of this slogan post mark, reveals that the cancellation was produced locally by the post office concerned from a master drawing. The alphabets of the word ?JAI HIND? in English and Hindi, varies from 61mm to 67mm, and the width varies from 11?mm to 15mm. 

There is something more in this slogan, which has attracted me. After checking/collecting 100 of this slogan, I have came to a conclusion that this post mark was withdrawn on 31st December 1947. And it was reintroduced from Girdikot P.O./Jodhpur for the first time in June 1948. That is why, this post mark, found after 31st December 1947, are mainly (say more than 95%) are from this post office only, and the remaining 5% are the late use of the post mark. The late use of any post mark can not be ruled out as it was done at the whim of Postal Clerks. We even find early India cancellations of the 19th Century on Independent India stamps. 

Another interesting finding is pointing towards a fact that this slogan was withdrawn from Girdikot (which was the second main P.O. of Jodhpur) in April 1949, but reappeared in June 1949 in a new format from Jodhpur P.O. the new format is in a rectangular box measuring 51mm x 26mm and also reads ?JAI HIND? in English and Hindi in two lines, with date, time and place in 3rd, 4th and 5th line respectively. The time and date are flanked with 3 wavy lines on each side. It was also used as a canceller. It remained in use until November 1955, according to my collection.

My collection of this post mark reveals that this slogan was used from the following Post offices.
