Set of four art cards issued by China Post (pre-printed postage), captioned only in Chinese, noted as “Humen Feeling,” by the artist Tan Zhu Yao (we’ve transliterated the name) from an art academy in Dongguan, Guangdong Province.  Our scan shows the fronts of three of the four cards; and the reverse of the fourth, which is the only card to have a “chop” from the Opium War Museum where they were bought.  The little brown strip holds all four cards together.  Grade: 1
