I picked this up a while ago. I had long admired the novel idea of a collapsible cup, but I waited to find one for a low price before picking one up. It's lost a lot of its nickel plating, but I can re-plate it here at home.
While the patent is 1890s, I'd think this one is a bit newer-- after 1900. Currently it sits on display on a corner.
My mom related to me that she had a green plastic one when she was a girl.
