This a in Nick Shinn's Figgins Sans Italic is really really cool.
The first time I saw it on Nick's website I thought Figgins?... Figgins probably never produced a lowercase sans, let alone a true italic a in sans. Very smart and a very successful super family. The whole Modern Suite that Shinn developped amazes me. I borrowed from my teacher a type specimen that Shinntype published I put some pictures on flickr
