"I don't have any idea how this card came to exist amongst my heaps of ephemera, but I'm very fond of it. It's either New Wave or Art Deco. I'm thinking because Mario had his phone number set using the old phone exchange, it might actually be from the 30's." — Carrie Hamilton

I also hoped this was a personal card — so blunt and mysterious — but in turns out that Mario was an Italian restaurant, operating in the 1930s–40s. Below is a postcard for the establishment postdated 1946. The location has housed various restaurants since. The current tenant is Sotto 13.
