Ahhh, ok, so it's just not me!! You're right, petrolheads will collect anything. The clothing I actively wear, but on reduced schedule/frequency to protect it's condition.

The media guides/kits which introduce the teams/drivers/cars I sometimes display them around the home, kinda like a season display or museum. I acquired most of the mediaguides by contacting the racing teams directly. The Jackets I bought on Ebay.

I expect the phone card are used/expired, but it's neat to see a touring car printed on one of those.
