Young Argentinian men in traditional costume drinking Mate, a traditional South American infused drink, prepared from steeping dried leaves of yerba mate (llex paraguariensis, known in Portuguese as erva mate) in hot water. Mate is served with a metal straw from a shared hollow calabash gourd (held in this shot by the gentleman second from left at rear). The other men can be seen holding their bomba/bombilla or drinking straws. Date: circa 1910s
