The factory pictured in the desert against a background of mountains may be part of the Corona Pressed Brick and Terra Cotta Company, which was formed in 1903 and closed before 1912. Made a half mile west of Corona, their bricks were impressed with the words "C.P.B. Co. Corona, Cal." The other pottery plant in or near Corona was the Pacific Clay Manufacturing Company. Printed in the bottom right corner on this German-made, divided back of the card is the publisher's number: 09 5829. According to the back, this card was "published exclusively for R. F. Billings, Corona, California." The date of this card would be from around 1907 to 1911 given the divided back and closure of the plant.
