Colour glass lantern slide of an illustration depicting progress in air, sea and road travel between circa 1900 and circa 1940. Made by Alex. Gunn & Sons, Melbourne Victoria, circa 1940s. One of a set of over 420 lantern slides, used by lecturer Walter S. Binks, a popular psychology and vocational guidance lecturer based in Melbourne, Victoria. Binks gave lectures throughout Australia in the 1930s and 1940s. Binks advertised his lectures as associated with the Australasian Opportunity League or Universal Opportunity League. Purchased by the donor at an opportunity shop. The collection was stored in three wooden trays (two compartments in each tray), and 95 slides stored separately. Many of the slides were produced in Melbourne from images and cuttings presumably supplied by Binks.
