I was just reading this thread again and have given this set some more thought recently. I am certainly in the camp of them being a set of candy cards rather than strip cards now as Lew Lipset (hi Lew) had stated. I still don't know about the two varieties being two different sets though.
Anything is possible and hopefully we will learn more about this set in the future. There has to be something about it in some old ad or something, you would think?
