To my disgust, it was just an envelope containing Entry Forms for the Derbyshire & Nottingham Rapidplays! The idiot who posted them has used an envelope slightly larger then the A5 format.
I am therefore assuming that many such envelopes have been sent out & that a lot of chess players have either:-
1/ Not bothered to pay the fee & collect the letter
2/ Are a little bit peeved like me.
Does anyone know who is responsible for this mailing shot?
