Auction Series 257-264 in Zurich Day 4

Suez Canal Company 1868 (July): 5 c. green, a used example, with large margins all round, cancelled by bold strike of "5105" gros chiffres of the French Post Office in Suez in black. A very scarce stamp in used condition, the strike being superb. The Gibbons catalogue price does not reflect the rarity of this usage. Cert. RPSL (1971) Gi = £ 500.
