Check out Jonathan's website for easy access to his ebay store. Currently he has up for auction (from his personal collection) a color photo of him as Caliban (played that the year before he got the role of Barnabas), a DS comic book and an unusual but great photo of Barnabas standing on the Old House "porch."
Of course, the performance DVD is for sale. Check out that offer on JF's website too.
