Collectibles signed by musicians. What do you have?

This isn’t signed, but I own the Suhr guitar shown in the video linked below. He starts playing it around 35 seconds into the video. I think Kevin Skaff got a contract with PRS, so he sold the Suhr. Sweet guitar.

The Who box set Phases signed by John Entwistle Porcupine Tree – Spiral Circus signed by all four members HSAS – Through The Fire signed by Sammy Hagar Mike Pinder – Among The Stars Nik Turner – Space Gypsy The Atomic Bitchwax signed by all three on first three LP’s

I bought a John Entwistle limited print at a John Entwistle art show in San Francisco about 25 years ago that John signed for me. Also have a cardboard 3 foot by 3 foot of the cover of Genesis' 'Duke', signed by Tony, Phil, and Mike.... 

I have quite a few things, including lps and cds signed by Patti Smith, Jorma Kaukonen, Peter Buck (REM), Glenn Tilbrook and Chris Difford (Squeeze), Graham Parker, Steve Forbert, Willie Nile, Garland Jeffries, Richard Thompson, The Jayhawks, Loudon Wainwright III, John Hiatt, Southside Johnny,  Suzanne Vega, The Roches, Patricia Barber, Toshiko Akiyoshi, John and Bucky Pizzarelli, etc., all seen in concert.  I also had Richie Havens sign a print of himself at Woodstock, a poster signed by Neil Young (from when he intoduced Pono), and a teashirt signed by Bruce Springsteen (from a friend who met him at Jack's Music Shop in Red Bank, NJ.

That’s fantastic! You guys have some cool stuff!

Over the years, I’ve acquired a few artist signed things, mostly from being at their show and seeing or meeting them afterwards. 
A signed CD from Mark Wood, CD signed by Amy Helm, a couple of albums signed by Beth Hart, a ticket stub signed by Elton John, a drum stick signed by John Mahon (Elton John Band) that he threw to me, Big, Beautiful Book of Bass book signed by Geddy Lee when I met him, a ticket stub signed by all 4 members of Lake Street Dive, a signed tour poster from the Tedeschi Trucks Band, a photo signed by photographer Lynn Goldsmith (Feet of The Beatles), Pete Best’s signature in a book “Beatles Gear” also signed by author and Chesterfield King member Andy Babiuk, a couple of photographs signed by photographer Baron Wolman when I met him at the site of the original Woodstock concert, and, I don’t know if this counts, but I bought an album from Tim LeFebvre (Who’s Hat is This?) that he was supposed to sign, but forgot. But, I’ve got the mailer he sent it to me in that he had wrote the address!
