Pics showing ok here, although you've blanked out the beginning of your number plate in one pic, and the end of it in the other pic, so people could still work out what it is
I've got some plate holders (slightly different to the ones shown, more like the ones in the Ebay link in the first post) but only use them for shows with my show plates in.
No pics at the mo as I'm not on my own computer, but you can just see it in my sig pic.
