He always got it correct the two times you sent cards imagine how many he has signed? Not always at his leisure sitting at a desk at home but at times with people shoving cards under his nose at functions etc.
I agree both the Barnes and Wells don't look like very good sigs so I would simply avoid them but looking at the sellers Provan and others they look fine to me.
That seller also had basically all the others, was considering to take the dogs ones if I didnt already have them, probably doesnt ahve a real handle on cards.
