The Poultry and Butter Market is in Princes street 1930. For those of you who don't know, Princess Street is the same street that the Exchange art gallery is today. The Butter market had been going since the 1800's. Butter was to be sold as 18 ounces to the pound but the butter makers shaved of ounces just before the markets opened to make better profits. Mr Penneck, the mayor and his constables raided the market in 1818 and seized any under weighted butter.
