A small documentary archive from 1972–73 relating to Princess Nina Mdivani Harwood, Baskervilles Investments, and designer‑silversmith Tony Laws. The papers include a Dorchester letter signed by Princess Nina (8 Oct 1972) discussing payment for designs and prototypes for a Sherlock Holmes key and key ring, along with correspondence between Baskervilles, Anthony Harwood, and Tony Laws Studio. Also included are layout sketches, logo concepts, receipts, and business letters from the same period. This is a paper archive only — no physical key or key ring. Interesting early evidence of Sherlock Holmes licensing and design work in the Conan Doyle family’s commercial era.
