Hollywood Boulevard, Christmas 1930 showing the two radio towers that the Warner Brothers added to their Warner’s Hollywood theater roof when they started KFWB. In so many photos of this era, there hardly seems to be any traffic, or at least compared to what we’re used to these days. But in this shot, we can also see how busy the traffic could get. My guess is that it’s due to the Christmas rush.

UPDATE FROM JIM HILLIKER:  Those antenna towers went up and in use on March 4, 1929 for KFWB’s 4th anniversary. Their first transmitting antenna was in front of the Warner Brothers Studio on Sunset Blvd. The 1929 KFWB antenna towers still stand, they were used until 1937 when another transmitter site was used near
Baldwin Hills. Jim Hilliker Los Angeles radio historian
