It only went for £31 because it was a variant - I only paid about £6 for it in a forbidden planet in Manchester so I was chuffed to bits.
They were done in series (pretty sure they only lasted 8) and the first set came out in 2005 made by Mezco with the characters Stewie, Brian, Peter, Lois, Chris and bedtime Stewie (Meg came in series 2 obviously :lol: )
I did have every single character in the first 4 series and got quite a bit of money for the 1st series, the only thing is Mezco re-released the first series in late 2006 still with the 2005 date on! It was crazy - Peter moc would sell for about £40 on ebay and then when these figures came out again he would go for about £20!
Really wish I kept Brian as he just looked brilliant
Not that i've kept up to date with them but it looks as though they have been totally re-released once more on a new look card as you can see in this ebay link:
