Correspondence with Welsh artists, art patrons and administrators of art institutions, together with annotated catalogues, ephemera and press cuttings, almost all relating to Winifred Coombe Tennant's activities as a patron of Welsh art and art in Wales. Throughout this group of papers are notes added by Alexander Coombe-Tennant.

Papers, 1843-1991, of the artist R. L. Gapper, including correspondence, plans and other material relating to artistic commissions undertaken by him; records and correspondence accumulated through his work as an administrator and adjudicator with the National Eisteddfod, and also as a lecturer in the University of Wales; and personal papers, including diaries and correspondence. Many of R. L. Gapper's own letters remain in the archive, since he often made copies of the letters he sent.
