When I went to England, I was going to London to see the MOMI "Behind the Sofa" exhibit, and a few other places where relics were located (like Longleat), and a few places where shows were filmed, but when I got to London, I found that the majority of the MOMI exhibit had gone on "tour", and I only saw a fraction of the stuff that had been in it. So I went on to Longleat, only to find that most of her stuff was in the MOMI exhibit that was on tour. She is the one who told me where the MOMI exhibit was, so after an extended visit with her, I set off for Bath to see the exhibit. I did still go to a few of the places to see where they filmed some of the episodes, too, but getting to see the MOMI exhibit was fantastic.
While I was visiting the woman at Longleat who owned the shop, she told me an interesting story. I had noticed a few cool posters that they had used to advertise the MOMI exhibit, and asked if she wanted to sell any of them. She said no, she was not interested in selling any of them, but said she did have something I might be interested in. She went into the back closet amongst all the stuff thrown on the floor and came out with a poster of a plunger that said "Find Out How It Conquered The Galaxy". It was a poster size picture of a sign that had hung across the bridge that led to the heart of London advertizing the exhibit, but on the first day up, it had caused such a traffic jam that they were told to take it down. So they took down the large sign, and all the small companiion posters. She gave me the poster.
I brought it home and matted and framed it and it is hanging up in my Dr. Who hallway display (much to my husband's chagrin.
