Hello NickClaret, welcome to the Glass Message Board.
A little tip to help you with the clarity of your picture of the signature... I have always found that it helps to rub a little talcum powder into the writing. It gets caught in the rough texture and can dramatically alter the look so that it is clearer to see. It will wash off easily and will not harm your glass.
Also, if possible if you can upload your pictures directly to the thread rather than through a link, it means that they will always be here for reference, and be of help to others in the future, whereas photobucket and Tinypic often just vanish, leaving the thread meaningless.
