I purchased this comic, Thor 148, through a reputable dealer. After looking it over I noticed it many of the edges were not close to straight and it was a lot smaller than a typical Silver age comic. It measures at most, less than 6 and 11/16" on both the top and bottom edges, about a quarter-inch smaller than most of my other Silver and early Bronze Age comics. Since I've been burned once before by a trimmed comic a lot more expensive than this one, I'm always a little skeptical. Admittedly, I'm certainly not an expert at detecting this, so I was hoping the boards could give their opinions.
Thanks, everyone!
