robert aSuppose several different products sponsered these issues and each product contained only certain colors.
What evidence do we have of this?
We know that most Old Puts are red.
We know that M131s are all blue.
I've seen many Blomes with blue backgrounds.
I've also heard from a couple collectors that have "found" sets that are all one color.
Have you seen any other evidence of this?
