I highly recommend this book for the history it will hold in years to come. I would have liked to have more bolts but i'm more than satisfied to have EPISODE III bolts and the signature of Trisha Biggar. Just as a note my number is 241.
Lucasfilm couldn't give everyone all the swatches, so they selected them at random. I think it's 7-8 swatches each person receives.
I think i recall reading it at Topic: Trisha Biggar Book
