What is the deal with backer cards!?!?
I also wanted to add to my comment... With some of the higher-end pins, artists now have signing events. A backer-card is absolutely imperative for this purpose. I would NEVER want an artists to sign the physical pin, but rather its card. It's like vintage baseball cards...it may be cool to have an old timer sign his card, but at the end of the day, unless is Mickey Mantle or Ruth, it will probably only devalue it.
