Sorry for the delay, I was out of town the last few days. The mugs and glasses are holding up well, though I must confess half of them are gone as guests have absconded with them(with my blessing).
I would be interested in two each of the Bird Sanctuary, Wolf's Head Oil, and Champion Spark Plug designs.
