The term picture bride refers to the practice in the early 20th century of immigrant workers (chiefly Japanese, Okinawan, and Korean) in Hawaii and the West Coast of the United States and Canada selecting brides from their native countries via a matchmaker, who paired bride and groom using only photographs and family recommendations of the possible candidates. This is an abbreviated form of the traditional matchmaking process and is similar in a number of ways to the concept of the mail-order bride.
