Manoj comics were published during 80-90’s and were loved by all its readers. But it could not withstand the rising competition and hence were lost in the pages of history. The primary reason I think why they went out of market was they had too many heroes and they never focused on any one. Apart from that they had parts in their comics. Still Ram Rahim and Hawaldar Bahadur were the best characters they had. Here are some rare comics 
2 Foot ki Rajkumari
Chamatkari taweez
