Handwritten letter signed by author of Count of Monte Cristo and The Three Musketeers

Handwritten letter signed by author of Count of Monte Cristo and The Three Musketeers, Alexandre Dumas, along with a First Edition set of his major works. Alexandre Dumas was born in Villes-Cotterêts.
BACKGROUND: His grandfather was a French nobleman, who had settled in Santo Domingo (now part of Haiti); his paternal grandmother, Marie-Cessette, was an Afro-Caribbean, who had been a black slave in the French colony (now part of Haiti). Dumas did not generally define himself as a black man and there is not much evidence that he encountered overt racism during his life. However, his works were popular among the 19th-century African-Americans, partly because in The Count of Monte-Cristo, the falsely imprisoned Edmond Dantès, may be read as a parable of emancipation. In a shorter work, Georges (1843, George), Dumas examined the question of race and colonialism. The main character, a half-French mulatto, leaves Mauritius to be educated in France, and returns to avenge himself for the affronts he had suffered as a boy -- order postcard of Dumas
