Thanks Barry, I kept these checked out of our library constantly in the late 50's. Mom & Dad finally got me a set ( $ 40.00 ) brand new in 1959 ! Lost them in a flooded basement accident in the 80's.
I own a set that had much wear and age. Received from a senior adult in Florida whose kids did not want them and wanted mom to get rid of them. I paid postage and they are now in my possession.
