‘Letters of all Shapes and Sizes’ trial sheetlets have surfaced lacking silver and with significant design differences to the issued sheetlets called ‘Letters on a Stamp on a Letter’ of 3 July 2003. The trial sheetlets feature a 25 March 2003 imprint (compared to 3 July 2003 of issued sheetlets) indicating release was delayed presumably to allow for various design alterations.
The trial sheetlets feature an illustrated background and lack silver from the stamps (Queen’s head, £5 value, and territory name). The trial sheetlet stamps have a ‘Lettersofallshapesandsizes’ inscription – absent from the issued stamps – and a royal blue background and pale orange frame compared to deep blue background and white frame of the issued stamps.
