I found a set of Adams Cups and Balls that have all blue cups. I have never seen this before. I have only seen them with red, yellow, and blue together.

Anyone know if these are the first plastic ones Adams made or what the deal is with them?

I grabbed them up because I found it unusual they are all blue, any information on these would be appreciated.

Yes they came in original ivory color box with instructions. Near mint condition. Lucky to have found super cheap price.
