Sometimes slightly inaccurately referred to as Leal Senado, this photo shows the iconic heart of urban Macau.  From personal experience, we can tell you:  there are never, ever this few people.  UNESCO World Heritage location.  Two cards are available.  One is unused (Grade: 1, $3).  The other was mailed in 2013, with stamp, postmark, and something written in Thai as a rubber-stamp marking (because the card went to Thailand) (Grade: 2, $6).
