This photo shows a parade. An old flatdeck truck is loaded with young girls wearing uniforms. The uniforms may represent Girl Guides, or their younger equivalent Brownies. The banner hanging from the truck reads, "50 years of service. In peace and war. Golden Jubilee of the IODE [Imperial Order of the Daughters of the Empire]. In the background is the Yukon Order Of Pioneers [YOOP] hall. This is likely the Discovery Day Parade.
