Glasgow magistrates had been invited to the Edinburgh International Exhibition in 1886 and were duly impressed by it. The first Glasgow International Exhibition was held in 1888. Valentine's were the official photographers for the 1938 Empire Exhibition at Glasgow's Bellahouston Park. It was quite usual to include figures in the pictures using photomontage. This was done to enable the organisers to sell postcards of 'busy exhibitions' on the opening day.
