It's originally the Sunday Strip #41 - The Crescent Cult (10-Apr-1955 to 07-Aug-1955) by McCoy which was printed in Indrajal comics as English tittle "The Lunar Cult".
Now a days, finding out such early numbers of Indrajal with all pages in good condition is not easy task. Many thanks to Abhishek Asthana who is supporting us providing his physical copies for scanning & Ajay Misra as always for scanning.
I'm not a photoshop professional, tried to make it better to preserve it for future as I understand there is very rare chances we can get better copies. This time I am saying about it, because I wish you criticized what you didn't like in these scans, it'll help me to make better mostly future posts.
74 years ago on February 17, 1936, the Phantom was first introduced to the world in a daily strip with the story "The Singh Brotherhood" AS GROWN UP person, but we say his birthday. OK, Happy Birthday Dear Phantom & Fans! :))
Hoping you'll like this Cover to cover version.
