The Maroussia Richardson Collection comprises papers relating to Richardson's mother, Betty Frank, and consists largely of letters by Frank to her mother, Amy Scorer, during Frank's tour of Australia and New Zealand as a member of Colonel W. de Basil's Monte Carlo Russian Ballet, 1936-1937. Frank danced with the company under the name Elisabeth Souvorova. There are also typed transcripts of the letters, together with photographs, newspaper cuttings, programs and related papers.
