It's a bit of cheap tat for a one off occasion that'll bring in a bit of cash. Well done the club, every little helps, just don't go selling them all year round or Cooper and the police will have a ****ing nightmare trying to identify the bloody hooligans who've snuck a can of coke in.
I've still got a few homemade ones I made for the Watford away game last season. I gave some away on the day (just a laminated printed face stuck onto 3D specs from the cinema).
