The information sheet identifies the 12p subject with Williams’s victory in the 1973 International Formula 750 cc TT race on the John Player Norton. Its 750 cc description is the race class; the stamp inscription gives the machine’s capacity as 748 cc. The card also draws attention to the Norton’s wheels, with five large spokes compared with the numerous wire spokes of older machines.<ref name="TT1975-sheet" />

== Production ==

The catalogue credits J. Nicholson as designer and John Waddington as printer. It describes multicoloured [[wikipedia:en:Lithography|lithographed]] stamps, perforated 13½, in sheets of 50 comprising two panes of 25 (5 × 5), with the imprint in the right-hand corner of the bottom margin.<ref name="SG2022-TT2" />

The accompanying information sheet gives the fuller credits J. H. Nicholson, R.I., P.S., and John Waddington of Kirkstall Ltd. It confirms lithography, five colours and sheets of 50 in two panes of 25. Its paper specification is 102 g/m² Litho-cromo 56b adhesive stamp paper. The printed stamp dimensions, 1.1 × 1.75 inches, convert to approximately 27.9 × 44.5 mm; the order follows the card and is not labelled width × height.<ref name="TT1975-sheet" />

The information sheet prints the perforation as 14, whereas the catalogue gives 13½. This discrepancy is retained explicitly; the card’s figure has not been substituted for the catalogue entry.<ref name="TT1975-sheet" /><ref name="SG2022-TT2" />

The catalogue records “1A, 1B, 1C, 1D (each ×5); 10p. 1A, 1B, 1C, 1D (each ×5)”. The separate 10p entry repeats the same plate numbers and multiplicity. These are issue production details, not plate markings identified on the illustrated covers.<ref name="SG2022-TT2" />

== Sales and withdrawal ==

The catalogue records 440,208 stamps sold for this denomination. Withdrawal from sale was on 27 May 1976. This is a stamp-sales quantity and withdrawal date, not a first day cover sales record or postal-invalidation date.<ref name="SG2022-TT2" />
