Hello and welcome.
Not a Fish, but a Cut-Ice Lollipop.
Would it be possible for you to take another pic of the signature, rubbing a little talcum powder over it with your thumb first, to bring it up?
It's not too easy to study it carefully in that image.
We do have lots of information and techie tips to help with resizing, here.
Do you have the very close-up setting on your camera? the portrait one with the flower icon? That would be the setting to use.http://www.glassmessages.com/index.php/topic,34093.0.html
We do appreciate the effort you've gone to, to post the images, and to resize, but I'm afraid they don't blow up big enough.
It helps to have a plain background too, and crop the images to eliminate excess.
Looking forward to seeing it a little better.
To find a rough valuation, you are best to search that well-known auction site for sold items, see what they've sold for in the past.
We don't really get involved with valuations here, they're far too subjective.
I am sure there is nothing wrong with it. It's almost exactly the same shape as mine and it looks like Michael Harris' work.
