Dated August 10th, 1957 comes this Ty Cobb hand signed envelope that once contained a letter to his doctor. Not only has this envelope been signed by Cobb, it contains his personal handwriting when he addressed the mail to his Doctor "Mr. 'Doc' Morris" in Menlo Park, CA. The envelope has been opened, and the tear has partially gone through Cobb's signature, but the signature is still clearly visible. Comes with full PSA LOA.
