SG 28 is the 10p Manx cat stamp in the Isle of Man pictorial definitive series, first issued on 5 July 1973.[2]
The design is credited to J. Nicholson. Courvoisier printed the stamp by photogravure in multiple colours on granite paper without a watermark. Perforation is 11½, and sheets contain 50 stamps (10 × 5).[2]
The issue information card for the four high values records stamp dimensions of 28 × 33 mm including perforation, five colours and special gumming for tropical climates. It credits artwork design to J. H. Nicholson, R.I. The card describes sheets of 50 as five stamps per row and ten rows (5 × 10), differing from the catalogue's 10 × 5 description; both source descriptions are retained pending clarification.[1]
