COAL publishes a monthly newsletter, Brushmark, that contains articles about coming shows and events, demonstrators, and featured artists. Brushmark also features editorials by the current board that give members inside information about the league and its events. Board member contact info and the current calendar can also be found in each issue. Brushmark is emailed to members during the third week of each month.
