As the cover says it is indeed a reprint of #305-1978 Antarikhsh Ke Daanav. I have this original version too, though with 4 missing pages. I find the original version quiet superior in print and in dialogue as well. I don't find any reason to change the original print and verbatim.The original version will also be posted subsequently. I shall be needing the help of fellow community for 4 missing pages though.
