Vintage 3.75X2.5 card signed, "You have it from his own deliverance and by other warranted testimony, Shakspere. Yours truly, William Warren." Interesting that he didn't know how to spell shakespeare.

William Warren (1812–1888) was an American actor. For decades he performed with the theatre at the old Boston Museum.

Comes with a full Letter of Authenticity from Todd Mueller Authentics if the lot sells for $10 or more.
