Congratulations on your success. I mailed a CD booklet to him nearly a year ago and no response yet. I suppose it's time to give it up as lost and try again.
I have been asked many times about trading / selling some of my autographs. I am sorry but my collection is not and will not be for sale.
I typically give a little over a year before re-sending unless there are a lot of success that take less time. Mine took a couple months. I would try again.
