Thirties design was amazing. I credit it to the 1927 demise of the Model T. With that pox finally dead, car makers were freed to stress individuality over manufacturing repetition. GM led the way, but the smaller builders were more free to pursue it. Chrysler was especially innovative, although not always with success, such as with this sales bomb that started the whole tear-drop craze:

Here are a few more images from the early Thirties:
