This charmingly illustrated Springbok by Hallmark 500 piece jigsaw puzzle is titled Merry Mousetown. It was produced in 1984, a year before Hallmark introduced the first in their very popular and long running line of Merry Mouse Christmas ornaments. Assembled size is 20-1/4 inches square. The puzzle is complete, the thick green-backed pieces are in good condition. The box lid has a little edge wear and a 1-1/2 inch split at the center of one lid flap.
