From the Phillips' website:
"More than 75 years ago, a young artist named Jacob Lawrence (1917–2000) set to work on an ambitious 60-panel series portraying the Great Migration, the movement between the World Wars of over a million African Americans from the rural South to the industrial North in search of a better life. The mass exodus prompted by wartime shortages and oppressive conditions for blacks in the South, was the largest population shift of African Americans since the time of slavery...The Phillips Collection presents all 60 panels of The Migration Series, reuniting the Phillips’s odd-numbered panels with the Museum of Modern Art’s even-numbered panels from their split acquisition in 1942."
