Fonds consists of photographs that illustrate Roméo Vachon’s early career as a mechanic and pilot. There is an item collected after the year of Roméo Vachon's death and so it is possible some of the material was gathered together in preparation for one of Georgette Vachon's publications. The fonds is arranged in three series: 1) Collected photographs; 2) Canadian Airways Limited photographs; and 3) Laurentide Air Service photographs.
