A notebook allegedly covered in human skin

A notebook allegedly covered in human skin, c. 1770-1850. The label reads: "The cover of this book is made of Tanned skin of the Negro whose Execution caused the War of Independence". This presumably refers to Crispus Attucks, who was the only black victim of the Boston Massacre of 1770, and who was immediately celebrated as an American hero. In 1888 a memorial to him was erected on Boston Common. If authentic, this exhibit might therefore, somewhat couterintuitively, suggest an act of honour and acclaim. Close examination suggests that the cover is probably not made of human skin.
