Delightful 1970s classroom posters

Lamentations about the troublesome aspects of School Days nostaglia aside, I wanted to share these images of some fabulous 1970s classroom posters that are currently for sale on eBay. According to the seller, they were part of a Highlights magazine series. If you're of my generation, this style of illustration will be very familiar. These were all over the walls of our elementary school classrooms; seeing them can definitely bring back those memories.

Here's a look at the images, which are now additionally saved here for posterity.
