A unique highlight is a 14K gold and gold quartz match safe purportedly given to King Leopold II of Belgium. Leopold II (1835-1909) is remembered for being, at the time, the world’s wealthiest monarch, and for being the personal owner of the Belgian Congo from 1885-1908. Leopold enticed American investors to the Congo using land grants that could include valuable commodities such as rubber. Henry I. Kowalsky, a San Francisco attorney, gifted this match safe to Leopold in 1900 in an act of self-promotion. The two began a correspondence that continued until 1904, at which point Kowalsky was hired by the king as a lobbyist to Congress on matters relating to the Congo. The match safe has a $55,000-$65,000 estimate.
