The collection consists mainly of photographs documenting many aspects of the early years of the oil industry in Trinidad. They include shots of the Aripero Well and other areas in Guagaguayare, which were the scene of Rust's pioneering efforts; clearing, drilling and shipping activities; steel derricks; housing areas; important events, for example the Governor's visit. Most of the photographs carry captions or explanations in pencil.

The collection includes correspondence, reports and miscellaneous information related to the Pitch Lake and the Trinidad Lake Asphalt Company. Also included are versions of a manuscript by D. C. Broome, The History and Technology of Trinidad Asphalt, 1972, 210 p.
