A time when there were no iPads yet, and children played outside.

Technologies of the 21st century have firmly entered not only our lives, but also the lives of our children. Now they master complex technology with lightning speed, call their grandmothers on Skype and put together puzzles on iPads, barely learning to stand on their feet. But just recently, armed with their own imagination instead of a smartphone, children played outside all day long, launched paper boats into the stream and actively explored the world. And only looking at these historical photographs, we clearly realize how much modern technology has changed childhood.
