South Africa 1940 3d Groote Schuur Imperf Pair Used

1940 3d Groote Schuur / Umbrella Tree COMPLETELY IMPERF (SG 59var). An attractive VF/U neatly cancelled right marginal horizontal pair of this rare error from issue 3. On small shaped piece, a barely discernible pressed horizontal crease at top (as often encountered on these, see images). A most desirable used piece for the specialist.
