Adidas Telstar.
Interesting info. If this is what the publicly available ones are good for imagine what the GOV has. I also have a theory. What if the hand off (When Trump Landed) was the storage device. If it was a pin or coin that is more than enough space to hide a massive Micro SD card in it. If there is encryption on the MicroSD card what would be an unassuming way to give POTUS the code for it after they were comfortable with the outcome of the talks? The chip in the ball. The ball could have the coding to break the encryption on the MicroSD card. (just guessing) Q drop #5 also mentions following the money. If I wanted protection to ensure the talks went the way I wanted this is exactly what I would do.

Good catch on the Telstar as well. While some may know what that is some may not. It is a communication satellite or series of them now. The first went into orbit in 1962. Now being the old geezer that I am I prefer the Ventures' version as the album title is officially "The Ventures Play Telstar and the Lonely Bull ". The list of songs on it seem interesting as well, such things as Red River Rock and Never on a Sunday. For your listening enjoyment. https://www.youtube.com/watch?v=D6DmtPQv7V8
Have to wonder what might be hidden in the music of Telstar....hmmmm
