Memorabilia needed for new illustrated Eagles book

Hi,
I'm writing a new celebration of the Eagles for Sterling Books called the Illustrated History of the Eagles. We want to use lots of original memorabilia- album sleeves, photos, singles, concert posters, ticket stubs etc and will scan your memories hi-res for the book and (and you of course), take great care of your posessions and give you a nice thanks and credit in the book.
If you can help please email me at andyjohnvaughan@yahoo.com
Thanks
Andy vaughan
