7/8” with lightly tanned backpaper by same Montreal maker as item #859. Shows civilian holding suitcase also inscribed with the letters “B.C.C. T.” which we believe stands for British Columbia Commercial Travelers, an organization of traveling salesmen. The “War Dance” was a fund raising effort. Salesman shakes hands with a uniformed soldier holding a British flag and with an artillery cannon at his left. To the right of the salesman is an early version of the Canadian flag and in the far distance is a ship with cloud accents. Lower foreground includes pine tree accent and wreath of foliage. Very tiny couple of surface wear marks show only in reflected light. Displays Mint. An outstanding WWI button and the only one we’ve seen.
