The Adler Trumpf Junior is a small family car introduced by the Frankfurt based auto-maker Adler, early in 1934. Trumpf Junior was conceived as a similar but smaller version of the Adler Trumpf, which had already been available for two years. It intended to broaden the range and claim a share of a growing market which DKW were creating with their F1 model, and its successors, for small inexpensive front wheel drive cars.
