Removing Permanent Marker from Clothing?

I am sorry to kick-start the thread again, but could do with some advice. I have a fully signed England shirt (in black permanent marker), which is great. Unfortunately at the top, it's signed "to all at XXX'', XXX being my work place. But I've been given it as a gift from management. Is there a way of removing the "to all at, etc." without removing any of the rest (signatures)? Thanks.
