Picked up this button at a con. I thought at a glance that it was Wonder Woman, but then upon second look, I have no idea who it is. Google turned up nothing, even when I tried various reverse image searches. Anyone know?
It is Wonder Woman - see this image from this pagethat has all the variants and when/where they’re from.
It’s a bit pixellated and stylized, but it might be a screencap-and-enlarge from an actual comic panel, which would explain the distortion.
Aha, sweet! I don’t have to turn in my geek card after all. Thanks!
No worries. It’s nice when the librarian researching powers and the super geeky comics powers combine to be useful. 
Found this t-shirt with the exact same Wonder Woman logo.
