Scanned a couple of photos of the house where I lived as a child in Calcutta between 1957 to 1975. Probably in the late 1960s or early 1970s a 20 storey block of apartments was built across the road from our house and it was called Tivoli Court. One of the photos taken from our upstairs verandah shows the corner of the flats and our front gate. The little house near the gate is where the guards or 'Derwans' lived.
The second photo is taken from the gate looking back at the house, I lived in the upper right corner and the offices for the Hooghly Ink Company were the entire ground floor.
The two colour photos were probably taken in the 1970s and the next photo in black and white was probably taken in the 1960s.
