All of the above are products are still being used to this day. What a great job by these inventors and the companies who got these products to the consumer. The sad part is that what goes up generally comes down and when the Great Depression hit, sales went south especially most of these products because they were wants not needs.
Note that the picture below of an old jungle gym would not pass muster in today's environment. Coincidentally, one child was falling when the photo was taken. Now I need to research if the child was okay. I'll circle back around to you on this. 😉
