Seal Rocks is a group of small rock formation islands in the Lands End area of the Outer Richmond District in western San Francisco, California.  They are located just offshore in the Pacific Ocean, at the north end of  Ocean Beach, near the Cliff House and Sutro Baths ruins.  The name is derived from the population of Steller’s and California sea lions, who haul out on the rocks.  wikipedia
   In 1910, a young restaurateur by the name of Louis Bush refurbished an old Mack Truck chassis, painted it blue and gray and began offering sightseeing tours around the City of Washington D.C.  Little did he know his earnest endeavors would help establish the world’s leading-sightseeing tour company, known today as the "Gray Line".  By 1926, the Gray Line had expanded to booming cities including New York, Chicago, Detroit, New Orleans, Los Angeles, San Francisco, as well as internationally.

   This is a great Real Photo of a group of tourists in front of their Gray Line bus.  The card is dated on the reverse, “Feb.9th, 1930”, no telling who wrote that though.  There is no attribution to a publisher or photographer but is was probable a Grey Line Promotional shot.  It is in good condition with intact corners and edges.  The image and reverse are clean and clear
