Note: This stamp is the right hand stamp of a horizontal pair with the example sold by Spink in November 1999, lot 1488. Only three pairs and three single examples have been recorded by us, suggesting that there were originally only ten pairs issued. This example has come from a collection formed in Macau in the 1930's.
