Well, I can tell you that THIS one won't be here long! This is my friends ball, she inherited it from her teacher friend, who passed away. She taught at a school in Kansas City and was a huge Chiefs fan. It was presented to her as a retirement gift in 1991. In wonderful condition with no cracks or dryness.
No smoke, musty, or odors of any kind. I had my appraiser look at it on my service, so I took a screenshot of what he said.
Perfect gift, man cave, or addition to your collection. I'm not sure if it will hold air, it has never been used, so I assume it will.
