Complete Side by Side Comparison
TLDR:
Noun Project vs Layer Vault vs Flat UI
If anyone notice other similar icons, I can update image with side by side comparison.
Thanks to fellow HNers for the links to the images. I just stuck it all together side by side.
Edit: Updated with more samples.
There's arguably the talking heads as well:

That talking head / speech bubble concept is generic:

The Noun Project also has a profile speech version, though with curved lines instead of the bubble: http://thenounproject.com/noun/speech/#icon-No1202
Flat UI's version might have been partially inspired by LayerVault, but it's far from identical. In fact, the Flat UI head is very similar to the Noun Project's head, similar to how the LayerVault's newspaper is similar to the Noun Project's.
I know that its a bit of a stretch but it wouldn't have surprised me if the head/bubble icon came up during the email conversation that preceded the DMCA being filed though.
Doesn't mean I agree with it, but if you're going to have everything that potentially infringes LV's work you might as well put the stupid ones too. Plus it's now missing which makes it a bit suspicious (though the replacement is far better IMO which would explain the head's absence too)
