If it is natural wear and the sun will turn the box blue on any 63 Topps card, I'm just looking for another example. Please post if you have one.

This is really not difficult or a contradiction. It's how the green ink responds to light. It will happen naturally if a card gets direct sunlight for long enough. You can also easily accelerate this process to make them in less than 48 hours with the right light setup. How is this difficult to understand?

You are welcome to believe whatever you want, it's America. You have a special snowflake if that makes you happy. If you want I'll pull out my half blue 1977 Topps Star Wars I created as my test subjects on Friday when I get home from a trip. You can find examples online easily, including previous threads here.
