One for our US readers (or rich fans who can hop on a plane at the moment's notice): if you're into all things Lost, then Disney's D23 (10-13 September at the convention centre in Anaheim) looks like the place to be.
Profiles In History, the world's largest memorabilia auctioneer, is serving up a special preview of their Summer 2010 auction, with a display of authentic props, costumes and set pieces including Kate's toy plane, Hurley's winning lottery ticket, Locke's hunting knife, Sawyer's letter and more. This four-day sneak preview will be at booth 1930 and runs from 9am to 5pm each day.
The auction itself (yes, you could eventually buy this stuff) will take place after the series finale next year.
Disney's D23 event takes place just across the street from Disneyland in California. If you're able to make it out there, you'll enjoy exhibits, screenings, presentations and interactive experiences from every part of massive Walt Disney Company. There'll be talks by people such as John "Pixar" Lasseter, readings, signings and exhibits. Robert Zemeckis and Tim Burton will be appearing too.
