I did a quick trip to Calgary and back on Friday and Saturday. It had a bit of everything thrown in: some buying, selling, trading, and even got to see a few good friends and a couple of great collections. These are the signs I brought back. The vertical porcelain Dunlop is 1933 and the horizontal tin Dunlop is 1931. Does anyone know how the Seiberling was displayed? I thought at first with the two holes along the one side that it had a bolt-on flange but with all the edge chipping maybe it is more likely to have had a frame around it. Cheers, Don.
