SOUTHERN RHODESIA 1924 SG1d Used ½d blue-green. vert pair, imperf between AND AT TOP (from a strip of three), used on parcel form piece

1924-29 Ωd blue-green, vertical pair ERROR IMPERFORATE BETWEEN AND AT TOP (where roughly separated), tied to piece of parcel form by part "(PARCELS) BULAWAYO" cds (Proud type PP3) and blue crayon stroke on upper stamp. Evidently from an imperforate between vert strip of three (= SG 1d), of which no used examples were known to Peetoom, so likely a unique survivor, and as such a most interesting and demonstrably commercial usage. BPA cert (2022), referencing SG 1d. [cf. SG 1b, imperf between vert pair, cat ¨®£1500 used. This is a different and rarer item.] - P223013363
