SG70 is the 12p stamp in the Isle of Man 50th Death Anniversary of Sir George Goldie issue, released on 9 September 1975.[1]
Design
The horizontal design shows a trading hulk, canoe and stern-wheel steamer on the River Niger, with a portrait of Goldie. The information sheet identifies the Royal Niger Company flag on the hulk and its badge on the steamer’s funnel. It explains that stern-wheel vessels were used for river trading and towing barges.[2]
The illustration is a cancelled detail from the collector’s Isle of Man – 50th Death Anniversary of Sir George Goldie – Official cover – 1975.[3]
Production
The catalogue credits G. Kneale as designer and Courvoisier as printer. It describes multicoloured stamps printed by photogravure on granite paper.[1]
The official information sheet supplies the fuller names G. V. H. Kneale and Helio Courvoisier. It specifies four colours for the 5½p and 12p values, and five for the 7p and 10p values. Its paper description is official white paper with coloured silk fibres and special gumming for tropical climates. Stamp size is printed as 25.73 × 35.96 mm; this order is retained without assigning width and height labels to the differently oriented designs.[2]
The catalogue records sheets of 50, arranged 10 × 5 for the 7p and 10p stamps and 5 × 10 for the other two values. The information sheet confirms sheets of 50.[1][2]
This denomination uses 4 colours and sheets of 50 arranged 5 × 10.[2][1]
Perforation discrepancy
The catalogue gives perforation 11½. The official information sheet prints 11½ × 11¾. Both source descriptions are recorded; the difference has not been resolved by measuring these stamps.[1][2]
Sales and withdrawal
The catalogue records 439,843 stamps sold for this denomination, with withdrawal from sale on 8 September 1976. These are stamp-sales figures and dates, not first day cover sales or postal-invalidation information.[1]
