The second photo was taken by Missoula photographer Edward H Boos. Boos operated in the Missoula and surrounding area some time earlier than McKay, and La Moose looks considerably younger in this shot, posing with his wife and child.
Again, La Moose is pictured in his finery. His family, too, is dressed up. Between his or her mother and father, Joe La Moose's child huddles, camera shy.
