So after reading that there is ANOTHER eBay seller releasing fake manufactured multiple cover error comics, I tried it myself. I've been collecting them when I can afford them, but have suspected it might be easy to make fakes for some time now, so I wanted to see how hard it would be. (Note, this copy is not for sale and if you see it for sale). I'm also finishing putting together a double guts version (that wouldn[t be possible with a manufactered error the way I'm doing it and I'll show you later why). I found a copy of a comic I have many multiples of (it's a title that nobody is going to loose sleep over), found a few copies that have the staples in the same location so the covers would match up. Used a couple of tools to unfold the staples back to just under 90 degrees and pulled the staples out. Put two covers over each other and made sure the holes lined up and put them back together. I'm sure if I put some tape over the tools it would be very difficult to detect it the staples have been removed. Another indicator may be that the guts hang and inside cover hang out past the outer covers. My best guess would be to see if the holes where the staples are are look "unnatural". Here's my result (for educational purposes only). So be warned when purchasing multiple cover comics that they may be faked...
