Lubalin Ampersand

Does anyone know the source of this ampersand? It shows up on google images, as the search for 'lubalin ampersand'. If it's custom - where did it originally appear?

Or if its a font, what is it?



This is obviously custom work by Herb Lubalin. I don’t know where it originally appeared. I doubt this form has made it into a font. You might like the ampersand in Pistilli Roman, recently revived as Eloquent.
