This is a collection of Yacowar’s art auction catalogues, predominantly for European and American art, ranging from the Old Masters to contemporary, representing a variety of mediums. Several of the catalogues include final price lists from the auctions.

This fonds contains the administrative records of the art gallery, including exhibition, extension, publicity materials, and correspondence with various artists' associations and organizations.

This collection consists of exhibition catalogues, posters, invitations and promotional ephemera, primarily (but not exclusively) from Canadian art galleries. The catalogues predominantly feature the work of Canadian artists, with some European and American artists (and minimal representation from Asian artists). The collection provides interesting documentation of the development of Canadian art across the country, including regional focus and to some extent, the development of interest in Indigenous art. In addition, the collection includes some auction catalogues, as well as items relating to advertising; art and design used in industry promotion; and industrial design.

This collection is comprised primarily of exhibition mailers, as well as samples of his work in the form of stamps and book covers.
