Not sure if Opportunity Vancouver can be referred to as a junk store treasure, but the 238 page glossy magazine, released in conjunction with the opening of Expo 86, does offer some glimpses into the city a quarter century ago.
Most of the glimpses come in the form of advertisements-- fully two-thirds of the magazine's pages are just that. But even amongst those, there is some comic relief to be found.
Much attention is paid to the usual 80s selling points of the city-- SkyTrain, BC Place, Canada Place. Then, inexplicably betwixt them all, is a two page photo spread entitled "Climbing the Black Tusk". It all gives the impression that this was very much a rushed publication without any editorial direction (or perhaps content) but one that is quite clearly unadulterated Vancouver boosterism!
