St. Bruno Flake in full-bent Kirsten with a very large Brissitt bowl. When I saw the prices that old, sealed tins are going for on EBay, I went to check my box-o-old-tins and coddle them little puppies of "gold". Well, one of my St. Bruno lids wasn't as concave as the other lids were. With moderate finger pressure, no twisting coin, it popped open. As I checked them just a few months back, I don't think much if any air got in, but now I suppose I'll have to smoke the damn stuff!
