A superb unmounted mint, with full original gum, four margin pair lettered 'LB LC', beautiful deep impression and pristine gum. A very rare multiple in this quality. It is most certainly one of the finest pairs of the world's first postage stamp we have ever handled. A very difficult printing plate to find in mint condition, never mind unmounted mint as a pair!
