Machin Definitive 'Treasure Chest' Booklet Pane

United Kingdom · 1989 · 4 x 19p

This booklet pane, known as 'Treasure Chest', features four 19p Machin definitive stamps. The design is the classic sculpted profile of Queen Elizabeth II by Arnold Machin, a ubiquitous image on British postage for decades. The pane's selvage (margin) is decorated with an illustration of a treasure chest, giving the item its popular name among collectors.

Issued in 1989, this pane was part of a series of decorative booklets intended to make purchasing stamps more appealing to the public and collectors. The Machin series itself is a landmark in philatelic design, having been in continuous use since 1967.
