How to tell a reprint from an original? 0

[Max Vebaneta]

Hey guys so I have come across a fantastic four 52 however I know that that issue had a reprint in 2006. I’ve been looking at picks of both the reprint and the original and I can’t seem to find a huge difference (haven’t seen the back of the reprint) is there some way of knowing it’s a reprint?

It's marked on the back cover. The reprint has a bright white box with UPC code on the back. 

I found an eBay auction that has images of the back and the inside cover- https://www.ebay.com/itm/Marvel-FANTASTIC-FOUR-52-NM-2006-COMIC-REPRINT-of-1st-Back-Panther-9-0/162730334967

Hope this helps!
