This auction brings together an exceptional offering of Great Britain philately, spanning the very earliest days of postal history through to some of the most celebrated classic issues of the Victorian era, and is further distinguished by the inclusion of the Steve McGill Grand Prix Collection of Machins.&nbsp; The breadth and quality on offer will appeal to the specialist collector, and with material that illustrates not only technical excellence but also the historical and artistic development of the British postal system. From evocative pre-stamp letters and Napoleonic War correspondence to iconic line-engraved rarities and imprimaturs, the sale has been carefully curated to present items of importance and lasting significance.&nbsp; Among the many highlights is the outstanding 1840 Two Pence Blue block of six (lot 1063), one of the great showpieces of classic British philately, offered with impeccable provenance. Equally remarkable is the unique 1d Black Plate 3 bearing a blue Studley undated double arc cancellation (lot 1041), an item of extraordinary rarity that will attract international attention.&nbsp; The sale also features an impressive range of Rainbow Trials and Ormond Hill die proofs alongside exceptional multiples such as the mint Plate 5 Penny Black block of six (lot 1047). Together with notable postal history, rare Mulready material and a wealth of exhibition-quality classic stamps, this auction represents a landmark opportunity for collectors to acquire some of the finest Great Britain material.&nbsp;<a class="ck-btn" target="_blank" rel="noopener noreferrer" href="https://competent-prize-bbe30fc6a2.media.strapiapp.com/S26002_GB_Insides_Online_367bb09168.pdf" download="download">View Catalogue</a>
