Harlem was a very important neighborhood in the photo movement during the early years of the 20th century. This is where the controversial workers’ film and photo league did its work. If you know nothing about this group I highly suggest you read about it here.
They sought to change the popover attitudes at the times of the ghettos through photos and documentary films. Among the group’s members was Aaron Siskind and Lewis Hines to name a few.
Now on to the book. at the corner of 97th & Park in Harlem is where the trains enter the underground. Right across the street from the this point is a park. Walk into the park and stay left. Follow the benches to the a trash can. Have a seat and lean back a little looking left and down. Your disguised book is slightly hidden in the bushes. Good luck and log it here.
