Fiction

In the Dutch aviation comics series "January Jones" the title heroine, a US racing pilot in the 1930s, flies and owns a de Havilland DH.88, usually indicated as (De Havilland) Comet. Its red-with-white colour and #43 resemble Grosvenor House.
This series has been published in Dutch, French, Danish, Norwegian, Finnish, Portuguese, Catalan, Spanish and German.
