SG 271 1/2d Bright Green (fine impression) M3 (6) corner marginal in Post Office fresh unmounted mint condition. Offered here with full benefit and additional security of accompanying, original RPS certificate 163270 when as a control strip of three.

A real clear example of why this stamp won the accolade of the "fine impression" tag though remember this should only apply to this shade 6 as the deeper shade 7 can often be a little blotchy.
