camlan - this continued in Canada way after the Depression. Until the middle 60s here in Alberta it was a law that margarine could not look like butter, and we, too, had the bags of white margarine with the orange button in the middle. My older sister and I once were tossing the bag back and forth in the living room. The bag fell, burst open, and the contents oozed all over the woven grass rug on the floor. Big mess!
