There is a man in history whose signature has only been found written out in six places. It did not seem to bother him that he never managed to spell his own last name the same way. Today we spell it William Shakespeare.
Spelling isn't everything.
-- There are six surviving signatures written by Shakespeare himself. These are all attached to legal documents. The six signatures appear on four documents:
a deposition in the Bellott v. Mountjoy case, dated May 11, 1612
the purchase of a house in Blackfriars, London, dated March 10, 1613
the mortgage of the same house, dated March 11, 1613
his Last Will & Testament, which contains three signatures, one on each page, dated March 25, 1616
The signatures appear as follows:
By me William Shakspeare. --
