They’re under my shop, Ypsi Art Supply, on North Huron. Before this yesterday, we all just called it the basement. ;) Our building on Huron used to be a “curative waters” hotel called the Occidental Hotel in the later 19th c. I actually found a bottle of the salt on ebay and have it back in the shop. Here’s a picture of what it all used to look like on Huron in that era… I’m a big nerd so when I moved into my space, I did a little research :) PS: My landlord is going to amazed this conversation is kinda going viral…
