Does anyone have an authentic Robin Williams autograph? I saw here that his secretary may be signing his autographs, but if anyone can confirm or opinions if any of these are authentic? I thought that maybe the last one (R1) is authentic because all he wrote was his name. Sorry the scans are so dark.
