Here are 2 links you might like to see. they are mostly found in areas where working class Europeans settled well over 100 years ago. Cincinnati had a very large community and it is there on the old houses and other buildings that the chimney pots have been found. As building are torn down, the chimney pots have been salvaged and have become collectible items. After all, they are antiques. Mine is on my walkway to my front door, usually with a flower pot on top. I had a double vented pot that was stolen one year just before Christmas. I twas worth money on the street to someone buying drugs.
