Fonds consists of material that reflects Charles van Sandwyk's development as an artist, illustrator and publisher of fine books in Vancouver. Materials include original artwork (watercolours, etchings), exhibition posters, book and book signing announcements, press proofs, broadsides, invitations, edition of the High Branch Society mail-outs (which include letters, cards, decorative envelopes, poems, and small copies of art), fabric banners, and medallions. Most of the items are signed by Charles. Some of these materials were brought together by Charles and the Joyce Williams Gallery; the arrangement of that material as it arrived has been maintained. Other materials were purchased from the creator and maintain the original order at the time of their acquisition.
