I would love to see pictures of this bad boy in 9.0. I am looking for a nice #139 myself right now.
Flash 139 also brings back great memories of the excitement/enchantment I felt when I first saw it on the comic rack at Ken's Variety on Wharncliffe Road in July of 1963. I mean I just had to buy it, and Aquaman 11, Atom 8, Justice League 22 and Wonder Woman 141 with it!
Here's the one I've had for more than twenty years.
I don't even try to guess it's technical grade, quite simply because I'm very satisfied with it as is.
I would be very satisfied with that also, nothing like raw high grade comics like that
