Hell yeah! Indiana Pacers are sending small fanpacks, which include 1 or 2 autographs, and a letter, and Sacramento Kings are more generous - they are sending autographs, fixture books, posters, t-shirts, and so on, and so on... I've got 2 packages from Pacers, and 7 from Sacramento, so try writing ...

I got over 600 autographs, but also other souvernirs... I'm collecting 4 years now, and I have 4 closets full of cool stuff But it never bores me, I will collect till I die
Some of the autographs are preprints, but most of 'em are real, sent from the celebs, or I have met them personally.
