I don’t have any more images from this set. I’ve seen just these two images being posted in many blogs/sites I look at, and I never noticed any reference to the name of the set or anything else that could help identify them. Try googling and see what you come up with. I’d love to see more of them too!
I’ve seen them described as “Alphabet cards used in Chicago public schools in the 1970s.” That’s as far as I’ve got though. I’ll let you know if I ever find more.

I googled “S is for Soul Sister” and found that the cards were designed by Edmund Erschen. I did not spend time looking for more of the images except there are some more of the set at: http://www.flickr.com/photos/erschenpaul/6204844904/in/photostream/
Genius!
O.K. I am posting the whole set, get ready internet!
Can you send me a link to where you posted them? Glad we could help each other out!

I thought they’d be a lot more popular than they are turning out to be.
Internet has been down due to an ice storm but back up now and I’ll check them out. Thanks for posting & letting me know!
