The early classic issues are very well represented, with a fine range of Bull’s Eyes including complete sets and multiples, such as the clear impression set (lot 2076) and the impressive 90r horizontal pair (lot 2078). These are complemented by an excellent showing of Slanting Figures, as well as Upright and Vertical Numerals. The section is further enhanced by a notable selection of Zeppelin and early airmail material, including rare airmail covers and destination mail (lots 2140–2152), and an appealing range of proofs, essays and specialised accumulations. Elsewhere in the sale, the extensive and carefully formed Ceylon collection (lot 2215) stands out as another significant offering, providing depth across both classic and later issues.&nbsp;<a class="ck-btn" target="_blank" rel="noopener noreferrer" href="https://competent-prize-bbe30fc6a2.media.strapiapp.com/S26001_Prices_Realised_1e3394f614.pdf">Prices Realised</a>
