Toni Booth from Collections Management was happy to take me on a little guided tour of Black Dyke. It's a foreboding place: floor upon floor of gigantic warehouse that puts you in mind of that final scene from Indiana Jones And The Last Crusade. Old TVs, movie posters, laserdiscs, computers, TV scenery and props... everywhere you look there's another fascinating treasure from media's past.
I had to keep my hands in my pockets, though. Pretty much everything is snugly smothered in bubblewrap and of course there is no touching on pain of something even more unpleasant than what people get when they open the Ark Of The Covenant.
35mm films. Hundreds of them. If you've seen 35mm film cannisters before, you'll realise that these relatively small discs don't contain enough film for full-length movies. That's because this is our archive of TV commericals.
This will trigger memories of Roland Rat and Mad Lizzie for those of a certain age. We've actually got another of these original logo boards from the 1980s TV-AM breakfast show hanging above TV Heaven at Bradford.
It's amazing what we found lurking in Black Dyke -- including this, the original animation set-up of animator Bob "Henry's Cat" Godfrey. Donated by Godfrey himself, it comes complete with the Apple II that controlled it all.
There's a store of videodiscs -- the gigantic precursors to DVDs -- at Black Dyke. These aren't the more commonly-known Laserdiscs: they're CEDs, developed by RCA and housed in a non-removable plastic caddy.
That's all just scraping the surface -- more pictures soon!
