Could be, he has FF#1 for example, and many more valuable comic books. 

Thanks for the answers, sadly he already shipped the comic book to cgc, so I can't take more photos. I also think is the masterpiece edition but his mother is sure they had the comic book in the 70's. The Indicia of the reprints was the same as the original, DC didn't changed a thing. 

This is from a friend, it was in the big collection of his father, which has many important comic books.  His mother tells him that his father had this comic before he was born in the 70's. The thing is that the number 1 in the cover looks different as other copies I've seen. Can someone tell me if this could be the original? Or which edition it is? Thank you.
