Probably an easy one but therefore an easy point to be earned?
What is happening here - two cars who appear to have ended up in a sea lion pool?
Also required is where and when.

Auto Wash Bowl,a very unusual car wash built in Chicago,1924.
The car was first run around in the pool of water to flush mud and dirt off of the undercarriage. It was then driven up into a stall and the car was washed in the normal matter to complete the job.
