One of the most visually arresting items in the entire Georgian Heads Series: illustrated at page 4/348. Ex Dr Leslie Abramovich, Charles Zuker and Arthur Gray. The ACSC states that these are the only examples in private hands, the adjoining CA Monogram block of 4 being in the Australia Post Archives.NB: the ACSC doesnt mention that this proof is on Single Watermark Paper. In fact, it is on the distinctive Rough Paper used for the 1920 printing that was issued only punctured OS! As a consequence of this previously unrecognised situation, the listing of this proof should be moved to before the Rough Paper printing, where it would be numbered BW #124PP(1). And, of course, this and the Australia Post block thus represent the only Rough Paper 5d stamps that are NOT punctured OS. .$20,00025,000210* 1/4d Turquoise-Blue marginal example with variety Thick 1 at right [1R57] fine mint, BW:128n - Cat.$600. $200300King George V HeadsLarge Multiple Wmk211** * d Green: A fine study on annotated pages including singles, blocks & pair, examples with Watermark Inverted and Plate varieties (some noted as per BW) with shades, positional pieces, etc. including 3 examples of the Thin fraction at right variety [65(5)s].
