One of these was brought up on here a while back. I think it's awesome and wish dealers would do the same today instead of trying to get me back into 4 more years of a payment. A nice little treasure you have.
haha, that is cool! according to a calculator I looked at on line, $7.00 in 1929 had the same buying power as $88.40 does today.
Postcards were used by automobile dealers throughout the country, most were factory provided to initiate sales of NEW cars, but also used cars and service work. This is a good example. I've seen some with pictures of a used car on the face and the price and sales pitch on the back side.
