Following up yesterday’s Preservation Photos #25 post, which featured the Giant Stride, here’s a glance at other unique playground equipment from the early 20th century. Of course there are many sources with great photographs and information, so consider this a sampling.
First, a search through the Library of Congress digital records always provides good entertainment:

With the digital world taking over, Flickr is a wonderful resource as well. People share their own images as well as scanning in magazines, advertisements, etc. By searching for “playground” in the uploads or the “playground” groups, you will find some awesome images. Most of it will be mid 20th century, not ca. 1910 or 1920, but it’s fascinating in a different way. Check out the sets by Nels_P_Olsen on Flickr for images of vintage defunct and surviving playgrounds.

More from the Miracle Playground Equipment catalog. I include this one for my sisters and our friends at Norwood Elementary: that thing we always called the spider web -- apparently it's a geodesic dome (note bottom). Source: Nels_P_Olsen, flickr (click).
For more, try the “old playground furniture” group. See also this August 26, 2009 “Playgrounds” post from PiP.
How’s that, Erin? Enough to hold you over? I’ll post more in the future. When you’re out exploring, be sure to let me know of any great old playgrounds! Let’s go build a giant stride in the backyard for now.
