Maurizio Boi, a regular contributor of photos of Lancia cars and commercials to Flickr, has added a set from a recent event in Genova. It includes a 1915 Theta and a Lambda. I'm quite liking the Bianchi as well. The bodywork on the Theta is particularly stylish. While you're there, take a look at some of his Lancia commercial sets.
