This photograph was taken in 1930. It shows children dressed up for the Brighton Carnival, a popular summer event in the early 20th century.
With digital images, we have all become used to the data and time of our photographs being automatically recorded.
But in the days of chemical photography, this information would be frequently lost or ingenious means would be required to record it. In this image a child is holding up a sign marked ‘July’.
Did the photographer merely wish to record the month of the photo? Or did the children carrying signs for the date and year wander off?
