Was this boy a real chimney sweep?

The photo on the left supposedly shows a child chimney sweep from the turn of the 20th century. But if you're wondering why he's not wearing any shoes and the soot on his face looks like it was applied deliberately, I may have found the answer: the photo is from 1980.

According to Getty Images the photo shows a four-year-old boy in London who's wearing a costume for a "fancy dress competition." The photo on the right shows actual child laborers at the turn of the 20th century. You'll notice a distinct difference in how happy they are to be working.
