There is a blank url for Shinola.com. I don’t know if anyone bought the trademark.
I think Shinola would be a good trademark to resurrect for a variety of products with humor, such as a toilet paper, political candidate faces on shoe polish tins and a website for awful products.
I think the phrase “He don’t know shit from Shinola” will be in the language for many more generations, especially if a product exists to carry it forward.
