This is an artist’s rendering of the Knott’s Berry Farm volcano, a well known and popular feature of the early days of the park.
The description on the back is written in a style resembling an actual message from the sender:
VOLCANO, GHOST TOWN
Knott’s Berry Place, Buena Park, California
This card cost me a nickel, but I think you and it are worth it. Never had so much fun as here in Ghost Town and would suggest to put Knott’s Berry Place on your list of places to go. This volcano is one of the many spectacular attractions on the grounds; it rumbles and belches smoke faithfully every night.
–In addition to the volcano, there is a small shack in front with a small mechanical demon inside that is said to operate the volcano. The structure was built in 1939, so this card likely dates from the 1940s.
