Do you happen to recall a previous post of the Whole Dam Family? No matter, I'll put it at the end of this post. The Whole Dam Family postcards were printed to publicize a movie entitled The Whole Dam Family and the Dam Dog. I am guessing that the following two cards were inspired by the Dam Family phenomenon.
First we have The Wurst Family. I never 'Sausage' Wursts.
Then we have the Gunn Family, with a message written in shorthand on the front.
Both of these cards were sent before 1907. There is no message on the back of the card because postal regulations didn't allow it until 1907. The first card was sent to David Kampf in Brooklyn, New York.
The second card was sent to Miss Lena Frink in Bryn Mawr, California.
Rootsweb, Lena Frink was born in 1881 in San Bernadino, California and died in Bryn Mawr, California in 1959.
Oh, and here's the Whole Dam Family, which may have served as the inspiration for the other two.
