Thank-you for that.

My intention is to frame the envelope with the note and now that I know the year I can see if I can get hold of one of the Christmas cards if I don't already have one. The Christmas cards were all of one design and were sold by the Brooklands Society which was set up in the late 1960's to promote the preservation and restoration of what was left of the Brooklands motor racing circuit at Weybridge in Surrey.
