Vienna Fingers

I was in the grocery store the other day and saw these cookies, so I took a photo for my friends back in Vienna. I thought you might find it amusing that we have cookies over here called Vienna Fingers. They are quite tasty - two vanilla cookies filled with creme. But I have no idea why they are called Vienna Fingers, as opposed to - say - Rome Fingers, or Paris Fingers, or Indianapolis Fingers for that matter. If anyone knows, please tell me!
