10 Shillings English - Afrikaans

South Africa's early Reserve Bank notes were issued bilingually from the outset — English and Afrikaans on the same face — a political accommodation reflecting the uneasy post-Union balance between the two white language communities. The bank had only been established in 1921, and by the time this series launched in 1928, note design and production had been contracted to Bradbury Wilkinson in Surrey, a relationship that would persist through multiple governor changes.

The date overprint on prefix E/12 — 17.11.1931 stamped over 02.04.1932 — is the most technically interesting variant in the run. Such overprints typically indicate notes prepared in advance for a scheduled issue date that was subsequently brought forward, with the earlier date applied by hand stamp rather than reprinting the batch.

Three governors signed across the series: Clegg, Postmus, and de Kock — the last carrying it through to 1947, the year before South Africa introduced decimalized predecessors.
