Here are some rare antique photos: the uppermost photo presents a long forgotten 1931 diplomatic event where Prince and Princess Takamatsu, as a gesture of international goodwill, are personally escorted down Pennsylvania Avenue by President Herbert Hoover. Left to right in photo: Japanese Ambassador to the U.S. Katsuji Debuchi speaks to President Hoover; Prince Takamatsu: Prince Takamatsu. Also included above are two earlier photos of Princess and Prince Takamatsu.
