Message on front reads - "When Santa calls this Christmas Eve, with pressies for my brother, I'll tell him Santa missed him out, and that he didn't bother! I'll hide them in a secret place, that he will never find, I'll tell him Santa passed him by, I know that's SO unkind! He'll cry & sob and stamp his feet, and then he'll start to whine, Oh, I'd better give them back to him.."
Message inside reads - "... or he'll want to play with MINE! Merry Christmas!"
