georgina (you know, alvin's wife) sent me this picture of a 'no unauthorised entry' sign because she thought it was amusing due to the severity of the expression. it is very good.

but i wonder if the chap looks a little alien like and he's about to zap humankind with his powerful black hand. i can understand people not wanting that kind of thing happening and it's surprising we don't have more of these anti-alien invasion signs about.
