International Reply Coupon 1927: Imperial type, Proof, imperforate
bottom left corner marginal block of four, printed on block cypher
watermarked paper, with "WATERLOW & SONS LIMITED LONDON" imprint,
without printing to reverse, from the original sheet of nine. Has
two vertical creases, one heavy through the left side pair which
has caused several pin holes, also the bottom left impression has a
hole above the ship mask and a surface rub in top border.
Nonetheless, an impressive showpiece. Reference: The Postal
Stationery of Nigeria, by Peter Hørlyck, illustrated on pg. 235
