Here is my post on the 1850 photo which now appears to be a photo of a model that - possibly has been enhanced at the top a a real aerial photo take at a later date. And here, from Kevin at LA OBSERVED is the photo that was taken in 1887.
The rest of the story is over at Nathan's LA Magazine column. The question then is - could one of the 13 views have been used to enhance the 1850 model below?
This may be the first aerial photo of LA
