The unique and extraordinay original sketch, by William Mulready, from which the design was adopted. Executed in ink on wove paper measuring 185 x 128 mm., the artwork, while being rather hastily prepared, shows numerous aspects incorporated in the finally accepted design, with the exception of a train crossing a viaduct at the base where the value tablet was eventually inserted. This item is, without doubt, one of the most important pieces of original artwork in Great Britain philately . Photo above and on front cover
