SOUTHERN RHODESIA 1924 SG2a var Mint 1d horiz gutter pair (R12/10-11) ERROR IMPERF BETWEEN, o.g.

1924-29 1d bright rose, lower marginal gutter horizontal pair (from R12/10-11) ERROR IMPERFORATE BETWEEN, fresh o.g. Much rarer than the "normal" 1d imperf between horiz pair (SG 2a), as all known examples of this variant appear to emanate from a single sheet (= 12 such pairs, at least four of which were used), making this positional pair unique. As such, a small thin in the bottom margin and the characteristic crease at right of gutter are of little importance.
