PUNCTURED 'OS': 1911-15 Monocolours Watermark Sideways (Crown to Left of 'A' as seen from the reverse) 2½d bright blue as SG O41 but on Thin Paper block of 4, unmounted, minor toning mostly on the perf tips at left, the U/R unit very fine. With a Thick Paper 2½d ultramarine for comparison. [Rosenblum states at p29 regarding printings on Thin Paper that "A very few sheets of this stamp were issued, O.S. only, about 1918 ... They are unknown without the O.S. puncture and even in that condition are extremely rare" (our emphasis); he also mentions that the Thin Paper being whiter resulted in "greater clarity of the inks" which in turn produced distinctive shades]

With a Thick Paper 6d brown for comparison. [Rosenblum states at p29 regarding printings on Thin Paper that "Again, a very few sheets were issued, O.S. only, about 1918. They are probably accounted for in exactly the same way as the 2½d and are equally rare" (our emphasis); he also mentions that the Thin Paper being whiter resulted in "greater clarity of the inks" which in turn produced distinctive shades]
