First up is this image taken on the Burbank lot in 1930, showing a truck with a "Human Billboard" for the First National/Vitaphone feature THE BAD MAN, starring Walter Huston.  (Alas, no human can be seen in this picture) Those familiar with the lot will notice that the water tower is seen in its original location next to the Power Station building (which still stands).  This rare photo was scanned from inside of Jack Warner's personal leather-bound copy of the script, which resided in his home library for decades.
