Removing Permanent Marker on a Signed Shirt

Please could you help 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, much appreciated.
