I got one nice return in the mail today.
Charles "Whammy" Douglas signed his 1959 Topps for me. I included $5 with my request.
For a long time, Mr. Douglas was a very tough autograph to get but started signing through the mail over the last couple of years for a small fee. Sometimes you still see a few of his signed cards on Ebay for over $100, but he's a very reliable signer these days.
