Provenance: Descended directly in the family of Mary Atwood Pool (1914-2009). Washington, DC, resident Mary Atwood Pool began collecting autographs of notable American historical figures at the age of 14, with each autograph acquired by her direct communication with the historical figure, their staff, family members, or attorneys. The consignor relates that this autograph was acquired from a Washington, DC, shop, and is the only item within the collection that Ms. Pool purchased.
