These are the ones made for time life?
In 1970?
Booklet by kaplan?
Owl on the back?
I've got a deck, they are cute.
They are the same pics as more modern ones with the owl on the back.
The poems are pretty dire.
They come up on Ebay pretty often, two in the UK right now.
Sometimes they go for about £10, sometimes far less, sometimes not at all.
There has been a run on them recently, I've seen loads.
Most have a blue back, but I have seen one set with a red back.
Mine are blue.
Hope this helps.
If you want the Ebay links I can send them PM.
