Vintage Japanese postcards are truly adorable. At the beginning of the 20th century, European style postcards became very popular in Japan. These Meiji era tiny masterpieces are more than just stationery. Many of them were distributed by the Japanese government to promote industrial modernization and growing military power. Collecting of Japanese antique postcards attracted great interest worldwide since 2002, after Leonard A. Lauder (the former CEO of The Estée Lauder Companies, Inc.), donated his collection of 20,000 unique postcards to the Boston Museum of Fine Arts. He began collecting them since the age of six.
