We do not know the reason why either of these mid-to-late twenties photos were taken, but it is likely that they were used for promotional purposes. The Packard Phaeton image above may have been taken for a Packard dealer or possibly for the Company itself. Note the two-tone wheels.
The Marmon below with a model pointing at the front suspension may have been used to bring attention to some new feature. If you can date and tell us the model of either car please let us know. The photos are courtesy of the USC Libraries.
