Official Word from Tim...
"It recently came to my attention that a warehouse sale, claiming to include "previously -owned" items of mine, is scheduled to take place. Allegedly, these items include props, memorabilia and costumes from various films I have directed, as well as some drawings of mine that were private gifts--never meant for public display or purchase. Since I have not been contacted by the sellers, it is important to note that I can in no way vouch for the authenticity of these items. I am completely against the selling of personal items in such a public way."
So if anyone was planning to go and possibly buy something, the items may or may not be authentic.
