This is a 1875 photograph of the first offices of the Los Angeles Times.
The label says it's the Downey block.

Again, I'm a bit confused.
I don't recognize this building in any of the photographs
I have of this area (and roughly in the same time period).
Perhaps this building was replaced by the building in the above photos.
I guess it's possible.....there is a 10 years difference from the above pics.
One clue (I guess you could call it that) is a banner on the Downey Block in the fifth photo in my post #534.
It says BOOKS.....perhaps it's the same company as in the above photograph but in a newer building.
Detail from post #534.
