Three registered covers, all to the Workman’s Compensation Board in Toronto, all franked with a single of the 20c Newsprint Industry and a 5c stamp of the period, being either a 5c Karsh, Wilding or 5c Scouting issue, to make up the 25c combined registration and forward mail rate. Includes both lighter and regular slate shades of the stamp, which was replaced by the 20c paper industry stamp in 1956. Very fine. Net est. $15.
