1941-48 1½d Gold Mine COMPOSITE PHOTOGRAPHIC PROOF (SG 87). A proof in the new size on perforated paper affixed on thick grey card, above a similar proof of the large format stamp. The front shows "Proofs # 79-80" in manuscript in red crayon and on the reverse in ink manuscript is written "Colonel Linton, This demonstrates the new design and size for the 1½d stamp as agreed by you over the phone. 25/3/41". An exceptional and unique proof.
