Chevron 7.8 is a UK Stargate convention that is taking place this weekend from 24th to 26th February 2012 in Heathrow, London. Guests attending are shown above.
I have also discovered that Showmasters (they run conventions in the UK) themselves are offering a new service where you can pre-order dedicated autographed prints from the stars attending their conventions. You can even order a signed canvas print along with the traditional 8x10 photo. Click Here to go the the store!
