Nub theory guesses please!

[AyeWhySwim]

What do people think? I'm not sure what I'm meant to be looking at! Thanks!

I can see one bit sticking up and one horizontal!

Anyone?

I don't think you can see the nub in this scan.. it's not the clearest. At a guess I'd say girl.

Girl I think x

Thanks! I agree it's not the clearest but I could see two things that I thought could be it. Might not be though! Both pointing different ways!
