Photo of the Sphinx taken from a balloon before it was excavated. I can't find a date, but based on when it was excavated and the history of photography, some time between 1840 and 1867
I looked all over for a date and got everything from "early 1800s" to "late 1800s" but nothing exact, so I had to make an educated guess. The first cameras practical enough to take such a photo were developed around 1840 and the excavations began in 1867.
I too was trying to find the date of this photo this week. To narrow your time span, the first aerial photograph (also from a balloon) was taken in 1858 in France. So this photo had to have been taken after that point.
