The Doorway print, the first official (read: David Lynch-approved) product made specially for the Twin Peaks: Fire Walk With Me 20th Anniversary Group Art Exhibition, is available for purchase. It is a replica of the original prop seen in Laura Palmer's bedroom, and comes in a limited edition of 100.
Laura Palmer and James Hurley's heart necklace makes a perfect Valentine's Day gift for Twin Peaks fans. The gold necklace costs only $7... and that's for both halves of the locket. If you're not going to wear it, then at least keep it safe in a coconut.
