Anyone else collect Comic Artist Convention Sketchbooks?

I've been building up a collection of these in the last little while, and it seems like many are evolving into full blown high quality art books. A far cry from the stapled kinkos booklets many artists used to slap together.

I've been collecting Frank Cho, Adam Hughes, J Scott Campbell, Bill Sienkiewicz, Darwyn Cooke, Jim Lee and a bunch of others.
