The original Mayflower Compact does not exist. What does exist is a handwritten copy of the Compact made by Mayflower passenger and Plymouth Colony governor William Bradford, made about 1630 in his manuscript history Of Plymouth Plantation. Below is a high resolution image of this page of Bradford's manuscript. Although this is in William Bradford's handwriting, the original was likely in the handwriting of John Carver. Below the Compact are scans of the original signatures of twelve of the Compact's original signers, gleaned from numerous different documents. Not all signers of the Mayflower Compact have known signatures existing today.
