Stuart Weitzman, the current owner of the world’s most expensive stamp – the unique British Guiana one-cent magenta – left his mark on the 163-year-old stamp this October.
Weitzman, who acquired the stamp for nearly $9.5 million US in 2014, joined some of the stamp’s previous eight owners in signing the iconic piece of postage. A renowned shoe designer and philanthropist, Weitzman added his “SW” initials plus a line drawing of a stiletto to the back of the stamp on Oct. 19, during a ceremony at the U.S.-based National Postal Museum.
Other markings on the back of the stamp were made by former owners Philipp von Ferrary; Arthur Hind (and later his ex-wife Ann, who won the stamp in a divorce settlement); Frederick Small; Finbar Kenny; Irwin Weinberg and associates; and John du Pont.
