1858 (July 21): 54 parale blue on greenish horizontally laid paper, a superb unused example with close but clear margin at right and huge margins on the other three sides, of excellent colour and appearance with tiny nick in right margin and slightest of vertical bends. A great rarity, surprisingly there are less unused examples of the 54 pa. than the 81 pa. known, with just 25 recorded thus. Illustrated and discussed in Heimbüchler, Vol. 1 on pages 300 and 301. A rare stamp for the classic specialist. Cert. Heimbüchler (2015) Gi = £ 21'000/Mi = € 22'000 Provenance: René Berlingin (March 1984), lot 12784.
