I can remember as a child, seeing news reels in school and before they would play the movies in the movie theaters. In those news reels, they would show worlds fairs with beautiful buildings, advanced technology, etc. The people were dressed in 1800-1900 style clothing that were walking around those world fairs. I remember wondering about all that and wanting to attend a world's fair. Now I wonder if those were not photos of worlds fairs but just everyday life in various cities! 🤔
