Green-tiled fireplace -- apparently a popular choice in the neighbourhood at the time. Our friends, Trudy and Errol, who are doing up a similar house a few blocks away, have the same cast iron fireplace, and Trudy tells me that they've had several chimney repairers, two of whom took photos, tell her they'd never seen that design or that crest before! Perhaps our houses were built by the same guys. Or at least they shopped at the same places (I suppose they didn't have the endless choices we do). Trudy thinks they might have the same green tile too!
