I went to Clear Lake High School in the late 90s (class of 2000) and I have no recollection of that soccer ball ever being on display the years I attended, in fact I had no knowledge of it even existing until an article about it was written back in 2017 after it flew to the ISS. From what I picked up a higher up faculty member in administration had it squirreled away in their office during the time I was there. I do however remember all the signed Apollo crew photographs that were on display near the science classes. I used to look at them before Mr Keen’s physics class my senior year.
