Count Dots and Receive Post Cards

April 20, 1916.  "By being careful and thinking, you can count the number of dots on this auto.  If you can do this, we will send you as a prize, a surprise  package of beautiful season and greeting post cards, lithographed in rich colors . . . ."  OH, how I would love to have those post cards!  I have never heard of an Overland Auto.
